I couldn't agree more. Even more or less it's a unfair gun for corner camping. When you shoot the player, the enemy can just run away behind a wall and just wait for you to move forward or make a mistake. It needs nerfing based on several annoying facts:
One shot, one hit kill
Shoots a lot farther than shot guns
Often used to beat assault weapons
Often used for camping to bait players
It encourages players using this weapon than having skill to use actual weapons.
