anyone here heard of Leo peek?

leo from guild keeps strafing until enemy shoots then kills them instead of stopping as you see an enemy. is this a real thing?

its situational imo. If an enemy catches you off guard its good to keep strafing while adjusting your crosshair (gives you slightly extra time while also making you harder to hit). Hopefully enemy misses his first shots and has to commit to spray, or wait for recoil reset, by the time you have your crosshair positioned on their head
