This is the stuff I would start with, not in any order. Important ones are in bold. [b]1. A greater focus on storytelling for the main game and expansions.[/b] [b]2. Tons of loot. Whatever Destiny has now x10.[/b] [b]3. Exotics that feel and look exotic. Useful unique perks etc.[/b] 4. Fire whoever designs the Titan armor. Almost all of it looks like shit. [b]5. Rewards that fit the activity and the players level. If you're at max level you should never see blue engrams/items.[/b] [b]6. Activity specific loot. For instance set items that can only be obtained from Nightfall, Raids, Strikes. We have a half-assed version of this now but it needs to be fleshed out.[/b] 7. A real reward for dailies. [b]8. Do not make all previous content obsolete when you release new content. It makes the game seem small and boring.[/b] 9. If you're going to have multiple towers have a way to fast travel between them. Nobody wants to load out to a loading screen to load into a loading screen to get to a tower, grab a bounty, and load out to a loading screen. [b]10. Separate PvP and PvE. They are two completely different game modes and neither should have to deal with the nerfs/buffs of the other.[/b] 11. Make a PvP mode with no supers, no heavy, and limited special. 12. PvP players shouldn't have to grind PvE content to stand a chance in PvP (not a PvP player but I bet this is something they want). 13. No currency caps. [b]14. Optional Matchmaking for all activities.[/b] 15. Four players instead of three for normal activities.
