1. I still think Bungie needs to build The Last City for us to walk through and immerse ourselves in. So we can see how life on Earth has been affected by the invasion of the Darkness. We can then see how humanity feels about the threat of the Hive/Fallen/Cabal and what they plan to do in preparation of fighting back as a community, whether they help stockpile weaponry for Guardians or just help build more homes for those that were affected by the invasion. 2. Adding our own personal space where we can show off our battle trophies like a Fallen Baron's/Archon's Energy Blades or a Cabal Generals Helmet like Valus Ta'aurc's Helmet. Or even a Hive Knights Sword. 3. Unique customisation to our weapons, adding of attachments, changing of armor. Add new pieces of armor, like shoulder armor being called Pauldrons and changing the name from Leg Armor to Greaves or just Boots. 4.They could also add a hangar, for us to customise our ships, so we could add cannons to it, or maybe change the look of the thrusters. These little things will give players that bit extra to fiddle with and add more depth and uniqueness to each character, instead of all players having very similar gear and vehicles.
