One thing besides the new fatigue system that the developers really messed up is the weapon sway. It's way too much sway to simulate the weapons handling of a professional soldier; it rather feels like I'm a 12-year old child soldier who has never before handled an assault rifle.
I mean, devs, really? Has any of you been to the army with live fire excersise training with an assault rifle? After even 1-2 times down the shooting range you learn to shoot very accurately from the crouch/knee position atleast up to 150m WITHOUT any scopes and you can control the sway far better than in the game even with a heavy rifle like the AK (we use an AK variant in our army).
Even when you go behind cover in crouch position and press "c" to support your weapon the sway is like a 10cm sinewave that goes all over the place... and no, being fatigued because of "fire&maneuver" doesn't make your hands tremble like a meth addicts and soldiers are taught to control their breathing in sync with their weapons.
So yeah, the new weapons sway is way over exaggerated to simulate the weapons handling of a professional soldier (or even a 12 month conscript like myself). I suggest for the devs to buy metallic airsoft guns and attach accelerometers to them and play a few rounds of pewpew if you never haven't had live fire assault excersise experience in your life.
