Team tactical. I used to play only that on black ops and i cant get used to bigger teams now but my K/D ratio is like 1.8 something now im on team tac so im not too bothered. Nice group of game modes available on it as well.
Lol, I use the second to last sniper rifle( idk what it's called) I throw an acog on the badass and reduce the kick. It's amazing.
