The bottom line, however, is that Blizzard continuing with the Mythic model in Legion seems to support my contention of class representation in endgame raiding. When a game has as many classes/specs as WoW does, it's much harder to design encounters that meet the perceived goal of the raiding experience in smaller fixed sizes. We can argue endlessly on that point (and that's largely the content of discussions in this thread) but there's no way for any of us can say which direction is most healthy for the game without injecting some amount of personal bias into our summation.
