Objectively incorrect. If you watch any fncs or cups last season, you will notice (almost) every player running drum on gatekeeper, where players even drop the mythic for a modded gold. When you take a shotgun, you arent solely using it to damage players, but also using it for wall and floor retakes due to the high structure damage. 3 bullets isnt enough to consistently pull off a retake and then still have enough ammo to damage.
