If you get a game with a bad connection where you lose every surprise encounter, when you pull the trigger before or at the same time as your enemy, start camping. Otherwise you'll go 1-14 if you try to run n gun.
What sucks for me is I usually start strong, like 4-0, when my team is facing their team then I go downhill after it turns into a furball and everybody is spread out and mixed up.
I need to learn the maps better. Seems like everywhere I go someone comes up behind and kills me.
