Even then, ask yourself this - would you rather something (like for instance, Kul Tiras) not show up, or it ending up in the game - only for the players to hate the implementation of, and eventually hate the whole thing? It's just something else I have a problem about. The community sets the bar unfuckingbelievably high for a lot of things, that if something we have longed for FINALLY ends up in the game, it's more than likely we will heavily dislike it and regard it as another failure.
For better or worse, Pandaria was a new direction for Blizz. No one here can realistically tell me they saw it coming before the patent was filed. It was clever, and proved that the already known bads aren't the only ones we necessarily have to deal with now. Also I'm not even sure why you brought up the Legion, as it doesn't really have anything to do with these posts, but ok?
