Let me explain: The shotguns themselves aren't OP, the way the game is PLAYED just caters to them. Think about it like this: In no other FPS game can you run up to a target so quickly and get within shotgun range of them. The shotguns in Crysis 3 have a reasonable range, the thing that makes them "overpowered" is the ability to get within that range so easily. Compared to your Call of Dutys and Battlefields, the Crysis shotguns have more versatility because there's more opportunity to get within killing range with the shotguns. So the weapon itself isn't overpowered, its just that the gameplay mechanics are suited too well to a shotgun player.
Anyone agree? Disagree? Let me know your thoughts.
