I don't think equipping full sets should add bonuses (I.e division).... Then you always have to wear that full set and look like everyone else. I think once you do acquire a full set you unlock an ability to equip. I think that would work. It would be another customizable slot that even includes an animation. Like the old blue fire head do completing nightfall. This would be amazing. Red eyes that increase range for having collected all siva raid gear. Taken fog that increase agility for having collected all kings fall raid gear. Yee.
