It definitely is a problem, but I just tend to let karma do its job There was a BTB match where a fellow teammate was attempting to kill me. I was still paying attention to my surroundings and noticed an enemy ghost thinking he could get a couple splatter kills, so I jumped out of the way while my teammate was still shooting at me and BAM, the team killer got splattered. I teabagged him and he proceeded to quit the game. Karma FTW
