Nope, Hackey's Right. Headlights is probably the most murderous weapon in the game. In the hands of a good player, It will tear your insides out and eat them alive (hows that for imagery :-)
Yes, right now we've had problems with friendly fire, new weapons, and skill rating. I gained +200 in a match when I went 3-5 and then lost +100 when I went 8-0. All these issues should be fixed in the coming update however.
