1. Horde or Firefight modes 2. Trading system. Color for Color only with a rest of any unlocked upgrades 3. A much longer raid with a more rewarding loot system 4. Customized exotics. Pick model, colors and perks. 5. More weapons and armor that go from zero to hero. Example would be Husk of the pit. 6. Nightfall cap set to twice a week instead of once 7. I'd say story, but I think we're too late for that right now. It'll have to wait until Destiny 2. 8. More PVE events like Queens Wrath for sure
