Luckily the guns that are too overpowered are gettng patched, its frustraing when you are aiming at a medic with your assault riflle and aim precisely at his head, shoot him, but then he sprays you and ends up getting a head shot, God i hate medics, specially the russian ones with the poopy face XD.
