Yes i've lost the odd hit in my time but not often. Only ever worked with legs, get clipped slide or kneel it's off the floor but when I do get hit it's cos i'm sticking out too far and it's 3 or 4 which is a bit much to lose. If you have a cheating gun which is set on purpose go home and don't come back till you can play well with others. If your inexperienced and picked the wrong setting get smacked on the head and told how to use it or set it properly.
If your playing against wipers shoot em again, and again, and again until they go off and then some more cos they like wiping so much the extra paint all over the pack will give them more joy off field.
