Not that this discussion belongs here, but WoW lost players with Cata. Not enough to shut them down. It would take the Titanic to do that.
Ironically, they lost those players partially by "catering to the minority of hardcores", according to many of the quitting posts. Then when they started nerfing, people quit because they were "catering to the casuals". The rest were "bored with the game", due to lack of new content.
Bottom line is, I'm tired of hearing the casual vs.hardcore argument. I move to a new game, and they follow me.
I just want the game to be fun.
