Would people be interested in a raid type event where your fireteam had to prevent wave after wave of various types of increasingly stronger adds from reaching the end destination. A tower defense type event. My idea would be a fireteam of 6. You start out with normal amounts of ammo. There are 3 rings, a white ring, a green ring, and a purple ring. Each ring color slowly refills your ammo while you stand in it, but only one ring can be used at a time and this is the only way to refill ammo. The map would be a typical tower defense map. Guardians would be up top and the adds would be on a path below. The difference is you can shoot from up top or go down onto the path if you wanted to use your super. THe challenging part would be coordinating who gets ammo and when and coordinating so all the energy types are covered.
