If anything Destiny screams for this idea. Something akin to Warzone from Halo. Have heavy ammo tied to elite enemies in a large map, bases where enemies defend that drip points like domination and sometimes spawn vehicles (seriously where are the tanks). Every kill gives your team points, but also the domination points, and killing major enemies (with the killing blow). Make one map with this game mode in mind and test it for an event. If we love it add more maps with later updates. Make the game mode either 6v6 or larger.

I had the same -blam!-in idea in D1. But more like a group of 10 maybe and had to defend 1 part of the wall for fallen entering the city. And their crawling down the walls and running in through holes. Also do almost the same thing in a raid where as your going through it you reach a checkpoint where you run into another fire team and have to work together to survive the onslaught of enemies. And when you finish you carry on and go your separate ways. And if you don't have another fireteam their in a few minutes then you still do the onslaught just with not alot of enemies.
