I think for Destiny 2 it would be a fun and novel idea if we could play as the different races that are involved with the story's gameplay. I don't mean playing as sweeper bot, but as the enemies. I want to play as a Fallen Vandal in a story line that has me trying to sabotage humanity's efforts in whatever they are trying to do. For example: Sepiks Prime Earth strike has guardians fighting against spider tank. It would be cool if I am able to play as a Vandal trying to protect spider tank and fend off the guardians.
