you have to watch at reg speed cuze he does it fast he will turn on and turns him to where the opp team memb. is then he walks around corner and shoots then just as they are about to turn the corner.
pre shooting doesn't mean the person is a hacker. I pre shoot all the damn time, based on the path I ran 2 get 2 the objective, I can determine roughly where on the map ppl are going 2 be, as can any 1 else.
