Even with a black belt in pump-fu, marking them doesn't usually change them. If anything you just get bonus balled more later. Yeah I've had to deal with dumbass players over the years like many people have. But in most cases it's one or two here and there. The squads seem to have a mob mentality to them. If one guys starts up the rest follow. I don't go out of my way to talk to them. I've had them approach me to check out my kp2 or other odd gear. This is when most of the problems start.
