A gunplay focused game like ArmA3 needs the baby-smooth movements it has, but it’s a bit like counter-strike for something like DayZ.

They don’t want DayZ to have an emphasis on gunplay, you’re going to spend most of your time in melee or stealthing. Indeed, gunplay will be exceeding painful for the player in injured stance, when you can only raise your gun from standing still. But they do want responsiveness, so it’s sort of an awkward marriage and they haven’t figured it out yet (source).
