1) next gen only. Forget the last gen consoles holding back the game 2) total matchmaking (opt out available). Do not restrict content because you don't have a team ready. 3) private lobbies in crucible (with customization options). Unranked/no leveling naturally (boost proofing). 4) no reforging. No 'ascending' gear. If similar rng system, make it so you have to hunt for the ideal roll or hunt to get the new version/higher grade version of your gear. 5) pvp element to patrol. Varied enemies/levels to patrols. 6) enhanced public events Really not much
