I have that happen to me sometimes. One or two potatoes that barely even move are almost un-kill-able. Then I look at the stats and they are terrible players. The game is doing funny sheznet with damage / given/taken in PVP matches. You ever get a 40 or 50 point lead, then all of a sudden can't kill the same people you were just wrecking? There is funny business going on behind the scenes. It's what makes the game so sweaty and being that guy that gets 30 kills and dying once feels empty. Or so bad when you can't do your normal damage and have to trail a teammate or hide in the corner. So many times I'm hoping my shots count. I know they are re-working PVP, but I'm not sure if they are going to address the core issues that they will never talk about.
