Do some thing with New Monarchy, Dead Orbit, and Future War Cult!
I wish they where still a part of the game.
I wish they where like they where in D1 where you joined one and earned a little bit of tokens with almost every thing you did.
I think it would be cool if the Factions had Crucible and Gambit events, if Rallies where reworked as a way to raise light, kinda like Iron Banner and if they too where involved with how the world evolves and changes over time. We could have escort missions or defense missions where we protect faction aligned civilians as they attempt to further that factions agenda.
Edit: one of my memories of Rise of Iron was doing the first mission in all New Monarchy gear. I loved that Auto Rifle.
