There also is the problem of Mean look+Baton pass I want you to solve.
Not entirely sure why you keep referring to this but given that Baton Pass doesn't carry Mean Look's effect and hasn't for the last (I think) two generations I don't think that's a problem worth getting worked up about

So as far as my own opinions are concerned, most of the movepools seem to have a mostly similar structure. All of them have Fire Blast, Hydro Pump, Will-O-Wisp, and Scald, at least thus far, and consequently most of them satisfy any minimum standard of competitive inclusion. Generally speaking, it's a good idea to differentiate your movepool in some way from every single other entry and then draw as much attention to it as possible (speaking of course as a voter who is looking for differences between broadly similar movepools; I am certain that someone who has actually won a movepool poll will be able to give advice from that angle). In the past this was done by including a particular combination of moves that no other movepool had, or indeed an illegality that no other movepool had courtesy of egg moves (which is no longer possible, of course). So yes, I am predicting that this movepool round will be decided by the odds and ends add-ons, in addition to the notoriously unpredictable flavour. For example, Qwilphish's movepool is currently the only (legal) one that has Pain Split but not Substitute. Which means that I personally won't be voting for that one, but I'm sure it will tickle somebody's fancy.
In trying to think of advice to give that is unique to a large number of very diverse movepools, I tried to rank them based on how I would personally vote if all were put up for PBV vote.

It's slightly hard to explain why this was weighted the way it was, as it comes down to a lot of conflicting factors like lack of Lava Plume/Overheat/Substitute/Swagger, subjectively troublesome flavour, and indeed the presentation itself, which of course was slightly lacking in the WIP cases. Oh, and also the fact that one or two movepools are presently illegal was not taken into account; I'm assuming that they will be made legal at some point through a non-contentious means.
Some specific comments are below:
--------
VAGUE AND UNHELPFUL FEEDBACK INCOMING (note that I may not repeat advice to different people so do read all of these if you want)
EpicUmbreon29: Your submission is still illegal based on too many RMs and certain illegal moves thrown in. Besides that, I'm having difficulty looking past the lack of Flamethrower and Surf, which I cannot quite see a reason for. You may want to try to justify that.
Salt the Flesh: Your Overheat calculation seems somewhat bizarre, simply because two turns of Fire Blast do more damage than two turns of Overheat regardless; I'm sure there are solid competitive reasons for lacking Overheat but your calculation hasn't justified that, so I would advise that you elaborate a little more on that section. That aside, I don't have any other competitive quibbles and your flavour is well thought-out.
V4LOVER: You've included just about every offensive option available, yet Return is for some reason absent from your TM list, which I presume is an oversight. Your flavour is enjoyably different, and you focus a bit on it, but you haven't really provided a sort of competitive vision for your movepool - it reads like a set of lists generated purely by looking at Volkraken. I'd advise implementing something like this, similar to jas, Deck, Korski, etc. Also maybe consider re-adding Swagger since it's terribly bad flavour to not have it.
jas61292: Man I really can't agree with you on only putting generic flavour moves in, that takes so much of the fun out of the movepool... yours is one of only two movepools with Poison Jab though, so I guess that's a plus. Also Octazooka. And Inferno. This makes it all the more annoying that I have no problem with any of your competitive choices, though I'm slightly disappointed that Baton Pass isn't an option. Also put Leech Life in please, or Absorb or something - if you did it would be my ideal movepool, really. Impeccably presented as always.
Deck Knight: Please get rid of the empty lines between moves; it's making your movepool next to impossible to read, and looks slightly sloppy as well (like you accidently copied and pasted from a site of some kind). As with jas I'm not keen on the ultra-generic Fire+Water level up movepool (I know you were going for the octopus motif but it still feels unimaginative), and again a reminder that egg legalities are somewhat irrelevant. Note that Choice Specs Modest Analytic-boosted Psybeam can OHKO standard Keldeo, so you might want to think twice about including it. Oh and note that Swagger is still considered an RM for this CAP and consequently you are 1 RM over the limit (I count 30 total).
EDIT: ginganinja said Psybeam is ok over IRC so ignore that
Dragonblaze052: As above, I'm slightly dubious about movepools including Psybeam. The flavour is nice but nothing special, and again I disagree with making Volkraken just another blended cephalopod Pokemon for its flavour since there are significant features to the Vampire Squid that make it stand out, or even the Nosferatu angle in general. You're lacking Double Team and Swagger, which are found on every ordinary Pokemon. As with Salt the Flesh, it would be nice if you could flesh out objections to Overheat beyond "wow too much" when the same can be said for Fire Blast in your Latios example.
EDIT: ginganinja said Psybeam is ok over IRC so ignore that
Kappaten: I'll suspend judgement on flavour until after you've had a chance to give reasoning. Personally I'm not fond of your over-reliance on Poison-type or ink-based moves for flavour. Also be sure to justify the lack of Lava Plume since that's turning me off your movepool at present. 8 egg moves is also rather a lot for a 6th gen Pokemon.
Qwilphish: Not fond of Substitute > Pain Split, not fond of the lack of Memento, not fond of the movepool flavour, but yours does definitely have some unquestionably unique points that serve to set it apart from all the others. Unfortunately, I disagree with almost all of them, but I applaud your individual submission.
Darth Missingno.: Where did your movepool go? I'm not going mad am I
Korski: Yours has almost the opposite problem to jas - I'm partial to your movepool flavour (not quite as much as Salt the Flesh or The Pizza Man but still good egg) but I'm not convinced by some of your competitive exclusions, namely the lack of Lava Plume and Overheat. That's not to say that this ruins your movepool - the comparison with jas was deliberate, in that any quibbles I have are tolerable, and that you have justified the lack of the aforementioned moves adequately - I agree that their inclusion might impinge on the "two sets only" ideal that you are striving for. It's not my favourite for the lack of those moves, but it's competitively sound and compellingly presented. I'd like to see some complementary flavour to the vampire angle in addition to Leech Life, such as Absorb or Bite.
Toebag: As has been said before, I'm not particularly convinced by the arguments for the exclusion of Overheat based on calculations involving the Lati twins since Overheat and Fire Blast do more or less the same thing. I certainly can't see how Overheat could kill them in fewer hits than Fire Blast given the lower Base Power over two turns (so I'd like to see more calculations supporting this position). I'm also not fond of the exclusion of Lava Plume. Again the flavour pool is slightly generic but moves like Spike Cannon and Captivate (I'm not sure I agree with the reasoning but hey) make it unique, which is good.
Ramplestilskin: Do remember to capitalise the second word of a move's name, as at present you have not done so. Also try to avoid overusing font effects; they make your movepool look a bit scruffy and unprofessional. 6 RMs in the egg move pool seems clustered and is wholly unnecessary; maybe move some of them to the level-up pool and add some general flavour moves to balance it out. I see that your movepool is the only one with Aromatherapy, though whether or not you want to highlight that is up to you.
The Pizza Man: As with the above, try not to overuse fonts; a simple asterisk will suffice in many cases. Also remember to fix any obvious spelling mistakes - making your movepool look presentable goes a long way. I like your movepool flavour, I like most of your competitive choices, and in all honesty if this only included Lava Plume it would probably be my favourite. Remember to justify why you don't have Lava Plume if and when you write up your full-movepool competitive explanation.
The Reptile: You have 28 level-up moves. That's three more than the Pokemon in-game with the most level-up moves, and certainly a lot more than most XY Pokemon. I'd recommend culling this a little. Again, I'm not fond of the whole Poison flavour angle, but to answer your question I do believe that ginga allowed physical coverage options for flavour (hopefully I didn't misunderstand) and Gunk Shot does nowt to just about every fairy around so I'm pretty sure it's ok. Egg moves seem fine. Competitively speaking I'm not keen on the lack of Lava Plume, so make sure to justify that.
escarlata: 8 total egg moves seems excessive. Your movepool flavour seems generic, but it's very well thought-out, so that's a positive. Competitively speaking, you should write a bit more describing competitive inclusions and exclusions as this seems a little thin on the ground at the moment.
----------------
And finally, some little things that I would like to see in these movepools:
- Play up the vampire angle. Yes, I know that "Volkraken" does not really reference the occult, but even so, it seems weird to have an artwork where a prominent feature is, well, the creepy pattern, and no acknowledgement of this in either name or movepool. It's not even a question of obscure biological knowledge (though I will admit I am a sucker for easter eggs like that); it's very simply a way of addressing this side of the Pokemon's flavour and perhaps more importantly differentiating Volkraken from similar Pokemon such as Octillery and Malamar. Yes, it's fine to take inspiration from various Pokemon, but some of the movepools I have seen don't seem to give Volkraken any identity other than the generic cephalopod treatment. I say "vampire angle" as opposed to "vampire squid angle" because the vampire is really the interesting bit, and indeed is not a difficult concept to grasp for the average Pokemon player.
- Do remember to include competitive justification, but perhaps more than that, don't just stick everything in hide tags. If there is some important competitive or flavour aspect to highlight, which you are particularly proud of or which gives your movepool a unique slant, add some sentences before the hide tag directing us to it and inviting us to see your elaboration. It's a lot easier to give feedback if your information is a) actually there and b) easily accessible.
- Do remember that Toxic, Hidden Power, Hyper Beam, Protect, Frustration, Return, Double Team, Facade, Rest, Attract, Round, Giga Impact, Swagger, Sleep Talk, Substitute, and Confide are all found on every normal Pokemon and more importantly that lacking any one of them is grounds for your movepool's disqualification (at least in theory - the rules have sort of gone up in smoke this time around). Hence, you would be well advised to justify any exclusion on competitive grounds, particularly as it pertains to Substitute and Swagger.
- As far as Type-Move and Move-Move combinations go, you should be sure to pay attention to them. While Solar Beam, Flame Charge, Blizzard, and Ice Beam are all illegal, Fire Blast, Flamethrower, Incinerate, Overheat, Sunny Day, Will-O-Wisp, Rain Dance, Scald, and Surf are all found on pretty much all Fire- or Water-type Pokemon and are legal (though you may have legitimate competitive concerns in some cases, of course). The Move-Move charts don't really say anything apart from the above.

right ok then that's all for now
EDIT: Oh right I forgot just to reiterate that
the movepool builder is a thing and helpful if you want to count RMs or just have all the resources available in one place
