There's really not much too elaborate here. Too often whenever I play a ROC strike, there's at least one person not playing the game and expecting everyone else to carry him. I can understand having to take a quick bathroom break or something, but when you're gone for over five minutes, then you're a detriment to the team. By that point, I'd rather you leave and let someone who'll actually help out take your place. I don't care if something comes up in real life or if there's an emergency; if that's the case, then turn off your damn console. Like in Left 4 Dead, there should be a vote to kick option. The rest of the team shouldn't have to deal with someone who doesn't help out at all. Is such a system prone to abuse? Sure, but I think the benefits outweigh the cons.
