This sounds like an amazing idea but if possible lets make it bigger scale! You know when Bungie does things they like to make them epic.... How about an Attack on Titan themed event? There are 3 walls that we must defend, the final being the wall to the city itself. We are being attacked by Fallen and (I can't remember if it's the Vex or Cabal that are theorized to team with the Fallen, but one of them) and it is our job to keep them from destroying the walls. All 3 walls up means Gold Tier completion, 2 walls remaining means Silver tier completion and 1 wall up is Bronze Tier completion. If every wall drops the event automatically ends. There have to be Devil Walkers and other heavy weaponry as this would be an event you'd expect many guardians to come attend. Thoughts or ideas for improvement?
