I'm not much of a PvP player anymore(to much lag) but I did some yesterday and considering the lag I still did OK. Got first on the losing team with 18 kills and a 1.38 k/d I think. All while using a suros that isn't fully upgraded. The slower ROF makes it almost like a fully auto scout rifle, easy headshots with a lot of impact and range. I was killed mostly by supers and grenades, the only gun that could kill me before I killed him was a thorn and that's only because the DoT got me.
