M1014 severely underpowered?

I have to say it is too op. Now you can kill people in mid range much better with shotgun than with any other weapon. Why not add a delay between shots? It is pretty unrealistic if you shoot 8 rounds of ammo in less than 1 sec and keep aiming perfectly. Doing so would also solve the damage problem: If you make the shotgun one-hit-killing in a short range (~5m?) but add a delay you would prevent noobs from running around and spamming everyone in their fov while still keeping the shotgun a useful weapon.
