I know you all might say "he is just better" but preactically having a weapon that is an effective shotgun, assault rifle and a sniper rifle is cheating.
The practice proves it.
Snipers can be "balanced" only if you are able to kill them as fast as they are able to. But you just cant. You can't have enough DPS to kill a sniper before he scopes in and clicks M1. Awaiting one-hit-kill headshots or making snipers unable to scope when hit.
