My biggest gripe with these game is how much time they take away from my other buddies who play them. I, in general, just really despise PvP games and the 'collect gear to be good enough to survive' mechanic sucks within the timeframe these games lock you into. I've been able to stay away from them without feeling any sort of 'I'm missing out' attitude, but I have lost some friends to these games exclusively and that kinda irks me.
