What people want is for Blizzard to address obvious bugs/oversights/gamebreaking mechanics/miserable conditions. They’re not asking for a new game.
The horde wanted horde-vs-horde queues because there is nothing fun about sitting in Shattrath for hours waiting for your queue to pop. Nor is it fun for the alliance who get ganked from air-borne horde who scour outlands looking for alliance levelers to gank between games. The latter also caused many alliance to flee horde-majority servers where the game had become almost unplayable. Nearly half of PvP servers are now single-faction.
Likewise, there is nothing fun about sitting in a group for an hour looking for a tank and not being able to find one. A few hours ago there were three Shadow Lab groups all looking for a tank. My group ended up paying a guy 50g to tank it because we got tired of waiting.
