this!!! its annoying that the armors are repeated, like Tika and Nuria said. Set-Stygian, Starmetal is the same as Ymir, Yog-dafari. It makes them feel less special, and not worth crafting with special materials if they are less useful, have no benefit or stat boost [which they should now with perks and armors with perks] but most of all, they arent visually unique. they all bother me because of that, ESPECIALLY Ymir = Starmetal. Even if Starmetal armor was at least visually automatically blue tinted like the weapons, that would be a slight break. but its not.
and a lot of the armors or pieces dont dye correctly. which is sad :(. the armors and artists who make them are AMAZING but i hope the repeating of sets is changed for some more uniqueness.
