You know I remember from games like metal gear solid? You can't sit there for very long and hard scope. Sure people can just do it in a half a second while doing a few backflips but for those who are hard scoping, there should be some sort of fatigue. You'd end up shaking a little bit thus forcing you to move.

Sniper Elite, control your breathing for a short time to steady and focus your aim, take too long and you'd be aswell sniping on a trampoline 😂
