Since there's the new Halo Wars 2, why not Destiny Wars or something like that? You control Guardians, Fallen, Hive, Vex, or Cabal in a skirmish fight and have your own Hero unit or an official Hero unit, like Atheon for the Vex, Oryx/Crota for the Hive and so on? And imagine your armies going on Strikes or Raids. It'll be awesome watching Fallen enter the Vault of Glass, and Cabal sieging deep within the Ascendant Realm within the Dreadnought and killing the soul of Oryx. Bungie make it happen plz
