Even though overall it takes 2 shots to kill an enemy, they are able to snap around and with a single shot take out out at almost any range, leading me to believe that even at 3000m+ they are consistently able to take a single headshot sometimes even out of rendering range of the server, this can be very annoying. Also after playing domination for close to a week, even machine gunners standing up can spray 20+ rounds down range and be 80% accurate with every shot.
