As we all know, when you fire the shotgun or the sniper rifles (without using the scope), the FOV jolts upward. Correct me if I'm wrong, but wouldn't it be more realistic if the recoil was part of the animation for each gun? What I mean is, instead of having the FOV shift, you would see the gun recoil, and your hands would automatically compensate for the movement. It's rather hard to explain, but IMHO it would look a lot better.
