I think you guys need to relax its just a game, and there are bound to be dicks and assholes durning online play.
Just finish the game, leave the lobby, and join back in with a different party. Not too hard guys.
I run into pricks all the time on avp, halo reach, and other shooters. there is a lot of them but c'mon don't complain about it, also theres a chance they might just be better than you although you don't realize it.
Just take a chill pill.
After all its a game, your not winning anything real just leave the match and find another party and enjoy yourselves. No point in holding somthing against a guy who is most likely 10-12 years old that happens to play better or play unfair.
Also if they have a group of friends what do you expect to happen? I mean c'mon. theres always a match were you get completely and totally screwed over.
Heck i get angry at the NPC's in the game more than the people who play it.
PS: I also know the importance of this thread but c'mon no sense in getting completely totally pissed about it, just put down his/her name and reason.
