Dance offs have already saved the universe once (see link), why not light up that Darkness with some stylish moves? Specifically, Bungie should build a [b]PvP dancing mode[/b], where you collect and/or unlock dance move Engrams that can be chained into a dance routine, or put together in combinations that unlock special moves. Then you could have dance battles in the Tower or in the Crucible, where two players compete for a combination of, say, player votes, perhaps in conjunction with hitting the right series of moves in sequence. Or for that matter even PvE, I think it would be cool to see what ill dance moves a Vandal could pull off with four arms. I have to believe that, since Guardians already dance, and they are naturally competitive warriors, dance battling is common in the Tower. Good way to work off stress between pushing back the darkness. And maybe participating in dancing battles rewards glimmer or marks or reputation. You gotta have moves in this here game. All I know is if you could mod Destiny, I would be working on this Mod as we speak.
