So does anyone else think it would be cool to have a cross over? Like a special Nightfall where your expecting to run into the Hive or Fallen and instead it's the -blam!-ing Covenant. Just imagine doing Summoning Pits expecting to run in and see the Hive but instead the room was full of Elites and Hunters... and instead of the normal boss it was the -blam!-ing giant Hammer Brute. Just sayin I think it would be a cool change, even if it was just for an event.
