The bonus couldn't be overwhelming though. Maybe 10% bonus damage to Taken when wearing the full KF gear with it stacking with the Will of Light bonus damage. Maybe 10% bonus rep when wearing a full set of DO/NM/FWC gear that stacks with the exotic bonus. Crucible/Iron Banner/Trials of Osiris gear could grant 5-10% more super energy when killing another Guardian. Vanguard gear could get more rep or increased damage to a random enemy race.
