Add the same guidelines for when someone quits during a match as you get when they fly out of bounds. Having people quit after they've been killed but before the round finishes is getting really old. Give em the -20, and give the last person to shoot them the kill. And while you are at it, fix the damn health/damage indicator; when someone has a sliver of green and gets shot 16 time w/o a shield up they shouldnt still be alive at the end of the round.
