Wow there is a lot going on with this thread, anyways I want to put in my thoughts since this is really such a huge project to undertake. (You must be really dedicated)
Overview: I would probably take out the first paragraph because all that tells about is Dragonite's past, and while I think that it was pertinent while the BW metagame was new, as we reach the middle to latter stages of the BW metagame I feel as if it is not as important, and really does not tell too much about Dragonite. I would put more emphasis on Dragonite being a very hard hitter while being bulky due to multiscale. I would probably take out the part that the metagame is more focused on bulk, because with all the new releases (a big part due to Tornadus-T), the metagame really has sped up. I really would stick to what Dragonite is good at; surviving almost any initial hit and then hitting hard. I think that this is fair to say because there are less defensive Dragonite's that do not invest in attack than there was before.
Offensive Dragon Dance: I probably would only give Ice Punch that smallest of mentions at the most in AC. The main problem with it is that it is really redundant with Dragonite’s main attack, and Kyurem proves that Ice and Dragon really are not the best coverage. It is only useful for pokes that are 4x weak to it as otherwise Outrage will be hitting harder. Go ahead and remove any Chandelure mentions as that is not relavant. When mentioning a Jolly Nature I would probably only mention Terrakion because Latios has a thirty-one percent chance of dying to a +2 Extremespeed while Starmie has a 87.5% chance of dying after one round of Stealth Rock.
Bulky Dragon Dance: I know that this is more of the second step of what your doing but I would move this set below Substitute+Dragon Dance because it seems much less solid in the current metagame. I would probably get more opinions on this set because I only ever played this set before Excadrill was banned, and yes, I can confirm that this set has not changed since before his ban.
Choice Band: I really would not mention Ice Punch for this set because this set is really doing two things, revenge killing with Extremespeed and hitting had with Outrage. Gliscor really is not the premier physical wall that it used to be anyway because of the rise in rain usage.
Substitute+Dragon Dance: I would keep this set as it is because this is really a more modern write-up and not much has changed in the BW metagame that would affect it.
Parashuffler: I agree with you that it seems pretty good as it is.
Mixed Attacker (Rain), Tank (Rain), Classic MixNite: I really am not experienced enough with these sets to give my opinion on them. (Really you can’t expect someone to try all of the Dragonite sets without setting out to do so)
Tank: I agree with you to question its viability. This set really is outclassed by some of the other sets and at some point you need to ask yourself that even though it is usable, is it simply due to Dragonite’s awesomeness through multiscale? Multiscale makes many sets of Dragonite useable but you should never use because they are outclassed by a different set.
Other Options: I would just add a small mention that even though Dragonite has a fantastic movepool, there are just things that you should never use because they are outclassed by another set.
Checks and Counters: Agree with all of the changes happening here.
I think that you got pretty much every thing that you need here, and good luck to this enormous undertaking.
