I think it would be really cool to create a raid or strike mission where you actually had to defend the Last City from the enemy. As I said, something akin to Helm's Deep where the odds are majorly stacked against us and we have our back against the wall. Another cool thing to do with this would be to add a community goal where the entire Destiny community needs to pull together and achieve a common goal. Whether it's to kill X number of enemies in that week or to successfully defend the city for a certain amount of time. At the end of the week, if the community reaches the goal everyone who successfully completed the mission would receive a bonus reward like a special emblem, shader, ascendant materials or maybe even a legendary engram. The reward tiers could also be based on what difficulty level you completed the mission at so people could feel like they are rewarded according to how hard they worked. This whole game has been about The Darkness closing in on us and pushing us back to the Last City. Surely they will bring the fight to us at some point so let us meet them in battle with guns ablaze! TL;DR Please add a Helm's Deep style mission where we can kill a bunch of enemies and earn sweet loot!
