How about more options, more choices than just one set? Sets center around one stat or another and also a relic passive loadout with the use of passives with more relic pieces the more passive bonuses on top of the stats the gear provides like set gear sets in other games when you get 2-3 pieces you get a set bonus and the more pieces you get the more bonuses are unlocked. they all can do high-end crafting just have to change around the crafting rotation based on the gear set. something along those lines
