Shotguns to op

Okay first off I find it funny how stupidly op the shotguns are for example the peacekeeper 90DMG body shot like what the f**k yeah I get it it's a shotgun it's suppost to do alot of damage upclose then how about the mastiff doing 77DMG 35m away like that's stupidly op it's very frustrating how the other guns you use have little effect upclose when going against a shotgun like it's painfully funny how op they are and they haven't been changed 30m almost 75DMG with 1 shot while my assault rifle does 14 for 1 shot and yes I get it Snipers do the same but no it's harder to land far shots then up close so yeah shotguns are to op
