I'm on a server where I don't know anyone. I don't like most people I meet in groups, you know why already. I don't like questing and groups aren't coming fast enough anymore, even on Bloodlust, to sustain my level of enjoyment.
I would need constant groups with not even good people; I would be completely happy with average people. The community would need to change and the mindset of the people who play WoW to keep me entertained and subscribing.
I don't want to quit, because I really wanted to get my Warlock to 80 before Cataclysm comes out. I think taking a month or so off from the game may be a good idea though. We shall see, I'm considering of going back to either Warhammer Online or Aion.
