1) Ammo Synthesis Constantly running out of heavy. Bring back ammo synthesis, and reduce that stupid timer for god's sake. 2) Random Rolls Duplicates have literally no purpose other than to provide legendary shards. The only problem with the D1 system was the complete lack of bad luck protection. Bring it back along with a method that gives the player some degree of control over what rolls they get. 3) Character (Re)Customization Improvements More hairstyles, the ability to pick our character's voice (stop with the whole "silent protagonist" shit, or at least have it be optional), and most importantly, the ability to RE-customize our characters after they've already been made. My Hunter's been stuck with the same lame-ass haircut since Day 1 back in 2014. I want to change it, but the only way for me to do that is to delete the character and start over. Since this character has been with me since day 1, I REALLY don't want to have to do that. 3B) Ghost Customization Let us choose our ghost's voice and give them a name. Furthermore, there should be more Ghost NPCs. It's a bit stupid how all of our ghosts have the exact same voice, they're all just called "Ghost", and the only other ghost we've ever actually spoken to has only just been introduced. 4) In-game Grimoire If Grimoire comes back, let us access it in-game through some kind of library area within the Tower. 5) Replay the Campaign Destiny 1 had nodes on the map where we could replay campaign missions and choose specific strikes to run. Destiny 2 should have that exact same feature, complete with Adventures and World Quests too. Furthermore, the game's prologue should also be replayable. 6) Restructure the entire Crucible Playlist system. Not being able to choose gametypes and having no system for voting on maps...it sucks.
