I think they should make a public event thats 2 days long, it should be an all out assault on the tower from the Cabal, Fallen, and Hive and every one is invovled in it. Different tiers of the event and maybe some automatic bounties. I thinkit would be pretty bad ass if we actually had to defend the last city. It would be fun to do different missions for the event but have it set up like a patrol if we wanted to do the missions. But all in all a huge tower defence public event would take this game to a whole nother level. Like get a message from the message master sayin they have intel of an attack on the tower and we have "x" amounts of days or hours to suit up and get ready for it. And at the end of those days or hours the Hive, Fallen, and Cabal crack the skies at the tower and they start assaulting. I think that would be dope. Once it starts yu can talk to the masters of yur class and yu can do different missions for them as well and completing their missions gives yu bonus exp for vangaurd or whoever yu do the mission for, and an exclusive item.
