It is not too smart to get killed by kill shooter. Had an idiot come from under me a couple of nights ago in a fast plane, get kill shooter, and get all bent out of shape about it. If kill shooter had been off, I would have gotten killed by someone I didn't (couldn't) even see because he was starving for a kill and hell bent on firing his guns. Totally his own damn fault, it wouldnt be fair to penalize someone else for something like this.
I can't remember the last time I was kill shootered, and I am sujre it is not even 3 times in the whole time I have played this game. It ain't perfect but it is better than any alternative ever proposed in the past 1,000 time this topic has been rehashed when someone didn't use the search function and post about it again.
