Tired of the same old team play

There should be a penalty for people just camping and sniping the whole time during an objective based game mode where the objective is to push objectives. Go play deathmatch or something. But sitting at our spawn and getting awesome kills seems to be more prudent than actually playing the game. Sure you got a 300m headshot, but we lost by 811 tickets, game was over in like 5 minutes...but it's all good because you got that one cool kill
