I would like tgis idea alot but it should be the entire set, ghost and artifact. Raid gear - extra super energy killing taken enemies. Faction gear - extra rep gain to that faction. Vanguard gear - extra rep to vanguard. ToO gear - extra glimmer when killing guardians in ToO. Or extra passage coins gained after a win or loss. PoE gear - extra rep to variks This is just my idea. I think these wouldnt be game breaking. Decent bonuses and it'd give a reason to have full sets.
