It would be nice to have a faction based Crucible match or game mode where in order to play, you've got to have a certain level of faction reputation, wear only faction gear and/or shaders, and can only use faction weapons. It would be a very interesting mix. Maybe throw in a faction exotic as the ultimate prize??? One or two for each faction would give gauardians something to work for. Right now there are three crucible factions and neither have a real purpose towards the actual game play other than having cool colored gear and weapons associated with that faction. Make it all useful.
