they really could improve movement by making the guns swing much more nicely when running, ive thought of something like swaying left and right, or bobbing up and down would be way nicer
the leaning mechanic could get nerfed in such a way that if firing while leaning, the recoil and inaccuracy would drastically increase, it would take a second and a half to be accurate with the gun after finishing with leaning or finishing the leaning sequence and being stationary.
there was a mere instantaneous prone long before they added a realistic slower prone, it could be something like that, but it would be way more complex to add.
ngl, what they need to add is soldier’s total equipment weight, and some basic graphs calculating how long the soldier’s running time is, his running speed, and so on
