Regarding the current metagame, I think we may be looking at a balanced BH meta though last-gen's eyes, where priority was rampant (and was considered as a bit broken in the end by many people including me). I don't think we can really know yet if the meta that many consider unbalanced is "broken checking broken" or just a big generationnal power creep due to many powerfull toys entering.
Obviously, there is some really broken shit like bubble, CFZ (only for the moment fortunately) and comatose, but the priority disruption play may just be a big playstyle change(which I'm not saying it is).
Still, saying that, for example, stall is dead is a bit permature as well. Extremely passive mons (Chansey...) haven't been seeing that much usage and thus testing. Innards out may be a great toy to just negate a threat, as a reliable D-Bond is something stall may love. Stall is always a thing that appears dead in early moments of any metagame then starts gaining viability.
In addition, regarding what may be needed to fix the metagame, the issue UselessCrabs has been describing with antipriority actually seems fixable by banning shell smash (as +1 sash things are way easier to handle than +2s, and power trip loses a ton of BP without Shell Smash). Once again, this isn't to say that banning Shell Smash is the way to go, but just that there as a few option to be considered and rushing into a suspect is a bad idea, although potentially necessary in the end*. Without massive setup, anti-priority sounds like imposter and previously shedinja, massively shaping the meta while being handlable and possibly bringing creativity (speed boost? scarf? alternate terrains?).
On the other hand, I don't really see any point in suspecting comatose. It is not something broken and OP, it is something uncompetitive. It, like moody, should in my opinion receive a quickban.
The main issue with the quickban seems to me that comatose may have some viability. My suggestion is to ban sleep talk, which has never had competitive viability. Just like gen6 assist, it creates incredibly polarizing matchup, as you have to use something like magic bounce Giratina+Audino to wall it. It admittedly is a viable core, but is still very restraining (and also invalidates pure offense).
An other virtue of this quickban would be that new players wouldn't get instantly disgusted by BH (I ragequitted AAA for a month after getting rekt by it). I am BEGGING everyone to not post a comatose team that people could use, because a low ladder with it is just kicking out all potential newcomers.
*dazzling and such may actually be the only things really worthy of a suspect where you could see on the ladder if the metagame improves or not when they are gone. Water bubbles, CFZ and comatose are, I believe, consensually considered as ban worthy and I would be surprised if the votes pro-ban got under 75% for any of these.
First of all, happy new year, and let me address my opinion of these, without any salt this time.
1) Water Bubble
I thought this was not broken due to the fact that it can be somewhat alleviated by running Water Absorb; however, the thing is, as many people have mentioned, most of the teams are currently forced to run a wall that resists Water type moves (which is still dented by Water Bubble) or Water Absorb.
Just like how Huge Power and Pure Power is broken as hell, Water Bubble is broken for same reason - doubling the damage while having no drawback is just something that destroys the equilibrium in the metagame.
The very first time I tried BH7, I thought two things were unbalanced and should be banned immediately:
Extreme Evo Boost and
Water Bubble.
I still remember the early game when I was confused about Primal Kyogre obliterating all of my team with Steam Eruption. And now Water Absorbers have huge trouble because of Core Enforcer, which is used to predict switch and make switch-in Water Absorber to be vulnerable to Steam Eruption or Water Spout.
In my personal opinion, the only viable way to stop Water Bubble user are these (probs not limited to):
* Water Absorb / Storm Drain / Dry Skin (??????????) - like previously mentioned
* Innards Out (something other than Chansey)
* Gimmicky set with Sash and Metal Burst
* Prankster D-Bond which is mostly a waste of a party slot
List of calculations that demonstrates the brokenness of Water Bubble:

If you need more let me know.
I don't think this problem will be resolved until either of these happen:
I) Ban Water Bubble.
II) Ban Primals.
I doubt anyone will disagree with me after all those calculations of evidence.
2) Comatose
Well,
I understand this can be a cancer if your team is unprepared. I think packing Magic Bounce / Defogger & Spinner / -Ate users, which are all fairly common, can deal with this issue.
3) Dazzling / QM
Interesting.
Virtually unstoppable without Prankster D-Bond or Haze. But what would happen if Imposter copies your set and starts sweeping your own team? You set up only to wipe out your own team. Gotta make your team Imposter - Proof, people. I might think about this thing as well though.
