When D1 vanilla launched we fought against Cabal, Vex, Fallen, and Hive. Here we are four years later in a sequel and an expansion and we are still fighting the same four aliens. (Taken are just reskins with swapped abilities) That's pathetic honestly if you think about it. Edit: LOL people are legitimately mad at the prospect of adding new enemies with new stories to this game. Where's your imagination? Here Bungie/Community this one's for free. A dark traveler shows up and creates a faction of evil guardians with Darkness instead of Light.
