There is now, thanks to MulleDK19. Please vote.Damn straight. I'd like to see the aiming deadzone sensitivity restored to what it was in ArmA 2 pre-OA.
Also note that it is now very difficult for us deadzone-using people to place units in certain areas because it's so damn hard to turn around with the mouse and the command cursor is no longer linked to where the weapon is pointing.
Cole, is there a ticket open for this?
