I believe weapon sway and inertia are realistic and necessary, but it is being implemented with one glaring flaw. I urge anyone who reads this post to grab your nearest rifle, airsoft gun, pellet gun, or even a broom. Shoulder the weapon/toy/cleaning device, then press your cheek hard against the stock. No matter how hard you breathe, or how much you move, as long as your cheek is welded to the stock, your optic will stay centered with very little movement. Your weapon will sway and your sight picture will move all over, but the optic stays centered! Now, in game the optic seems to magically wobble all over the place even when aiming down sights. This makes me feel drunk and uncomfortable. I suggest that you maintain the inertia and the amount of sway, but keep the optic in the center of the screen, moving only slightly.
