Currently there is no benefit to standing straight up, crouched or prone they're all the same. You should have max gun sway when standing straight up, and when crouched you should have less sway and prone you should have very little sway. This prevents people from playing unrealistically and benefits players who take the time to get better positioning instead of mindlessly holding the hold breath key and negating all sway of their gun. Speaking of holding breath, NERF that! In a game where you can be one tapped why should it be so easy to shoot, my suggestion it to pair it with the stance sway but also make it so it doesnt completely remove the sway just significantly reduce it down. Also after running for a while your character should not be able to hold their breath but have to wait maybe 20 - 30 seconds until they use the machanic again.

Some other unrelated small suggestions:

-When leaning force walk
-Switching to two handed guns should force walk player
-Make hip fire more inaccurate
-Gun melee shouldnt be instant
-Restraints should be 10x harder to get out of
-Melee headshots should do more damage and have high KO rate(currently there is no head hitbox on players for melee)
-Able to break bones with melees
-Ragdoll physics
-Add ATC tower to Balota airfield(its boring)
-Run swing with high ping getting crazy far connections
