Doesn't help the lack of muscle memory necessary for executing precise maneuvers in high stress situations
I don't know about that guy but the thing kicking my ass is the control scheme. Using arrows instead of WASD is an easy enough adjustment but having slide/jump/shoot all on my left hand, all right next to each other makes me scramble like crazy at any sight of trouble. I slide instead of jumping, jump instead of shooting and try to switch weapons at random because my muscle memory reflexively places my fingers at asd! Matter of adjustment I'm sure, but something to consider
