Slightly buff three of coins. Increase chances of exotic engrams being weapons. Give strike specific armor and weapons a special perk that no other weapon or armor has. (example: imago loop regenerates ammo on headshots and headshots give extra super energy) Challenge modes on old raids. New social areas ( such as areas down in the city) and new vendors (example: legendary trader). War modes ( command AI soldiers in all out warfare) More relics (the Aegis) More [i] interesting [/i] exotics. Those are my thoughts for now Edit: every few months crucible and vanguard vendors should change perks. Private crucible matches/ custom game modes.
