2 through the smoke headshots with a pistol on inferno. both these kills happened during the same game on 2 different rounds. fortunately the other team didnt make a big deal otherwise I might have to go on a VACation
I think the problem with dynamic crosshair(i refer to the big spread, the small spread one is ok) is that it's harder to aim accurately when it's expanding. The smaller dynamic crosshair is ok I think(i see many pros using it) but I never seen a pro use large dynamic.
I'm currently using a dot only, works great for me. I often had problems with a classic cross hair blocking the sight. Specially on distance it blocks everything. For example if you try to retake on dust from long,or cover short from bmb place
