Locating people with suppressors is seemingly impossible most of the time, even when they hit you there is no clear indication of the direction that you were even shot from, there are no markers or anything of the sort which even remotely reports a rough direction of the shooter, you're simply left with a bloody screen and no idea of what side of the body you were even hit.
This is extremely game breaking in my opinion, I understand that suppressors are meant to be hard to locate but this is just damn near impossible, not to mention the directional audio is lacking, especially in comparison to Arma 2, I see people spinning all the time trying to locate someone even after several shots have been fired.
