Now I don't mind that he emots "enemy down" everytime a bot kills me nor do I mind him getting to a PSP first just not to take it so he can kill bots while others make their way to that PSP (happened twice in the same map, will provided screenshots the next time he does it). I don't even mind the fact that I've seen him camp spawn points with blade in hand.
What I do mind is his frequent grenades thrown on my satchels. I've already died from it and I would like to see it stopped.
