Aiming deadzone is much much better now, not perfect but really more useable, problem that when you move you have to reaim all the time cause of the sight recentered all the time when you stop. It's not happen without the aiming deadzone, the sight is always in the center of the screen.
It's not really efficient like now cause if you aim somewhere in direction of an ennemy or where you think is he and you move you have always to reaim if your sight wasn't centered.
