A gun should do the same damage as another gun given it’s setup the same.
A coachman with the same mods as another coachman should do the same damage.
But make it “Rarer” and suddenly it does more damage? How?
The receivers in Fo4, I could forgive for game-play purposes, maybe you could reload your brass with more powder or whatever, but the rarity system just doesn’t make sense, and honestly pisses me off.
I don’t disagree. Those guns could use bigger and more expensive ammo also.
