I agree that there's limits of how much swag a weapon/armor should have. But this is also a fantasy game, so there should be more to it than regular, real items. I'm going to design a weapon, but I've not yet decided how it should look and I still don't know how much I can edit it. It says in the reward tier that the weapon/armor have to "be within reason", so I don't think you'll see very flashy gear in the final game.
