Shooting a weapon in prone is very difficult on the XBOX and this could also be the case on PC.
When you try aiming, it feels very clunky and slow to move your camera and crosshair around, sometimes you can't even move your gun while moving your crosshair around.
Also, the gun is usually misaligned with the crosshair, a heavy amount.
When you go ADS, you aim much lower or higher than where your crosshair is, which is frustrating
