One thing I really find annoying in this game is that turrets have huge hitboxes. It's impossible to shoot enemies when they are ducked or proned behind a turret. The walls seem to also have these problem, the BE wall at least, not sure about NF. I sometimes try to shoot round the corner and hit the wall when I'm not aiming at it. This also happens with a lot of objects, like crates and rocks, in maps, like the crates in escort. Please make them smaller.
