Well let's think of games that involve a bit of strategy to win that are fps; we have halo and battlefield. (Not counting destiny because not technically out yet) in either of these games our campers common, yes but only when they should be aka sniping. The only time you're helping your team whilst camping is sniping otherwise you're a selfish bitch who only cares about getting more kills through unskilled means. If you want to help your team win you play the -blam!-ing objective (not counting tdm because tdm is just mindless shooting with no skill or point to it)
