Oh, nothing. I'm just a bitter former WoW player who really enjoyed the game's aerial combat, the underwater raid and the Path of the Titans progression system...
Granted Blizz has gotten better by simply promising less, in the past the game boxes had screenshots of features on them that didn't make it into the game.
Aerial combat wouldn't have been that fun, either with vehicles or just floating around. The playerbase hated Vashj'r (wrongly) so that's why they just left the Neptulon story unfinished. But yeah, after WoD's cuts, I'll just be skeptical about how awesome the new stuff will be. Well and how much they gate things by time or grinding for points
