I think the same. Seems that they are not here to play nice. The only thing they want is to fire on everybody without asking. just kill kill kill. This is not a "go and kill everybody in sight game", well i think it is not. There are other games for that, FPS.
The abusive way to talk (and discriminate) of those guys is intolerable. They should be more polite, instead of going attacking people, cheating, and bitching if the enemy poses a threat.
