Exclusivity to current gen (Xbox One, PS4), so we can have nothing held back. Sorry PS3/360 users, its nearly 2 years now. Its time to upgrade or get left behind. Integrated Grimoire system in the game like what Mass Effect did. More cohesive story with more cutscenes to actually tell us what the -blam!- is going on. Separate PvP with custom loadouts and weapons exclusive to PvP. So we can stop all the nerfs to weapons which heavily effect PVE, the main reason why people play Destiny. With the changes the House of Wolves is getting, Destiny 2 might be what Assassin's Creed 2 was to the original game.
