Wholeheartedly agree. Like many here I enjoy the game, but it could be better. The concept of calling the guardians back to defend The City or even a mission to establish an outpost would be awesome. I think if our individual actions somehow contributed to the Destiny universe as a whole it would add to the satisfaction that we're actually doing something. Bungie has the data on our stats that could be used to compile whether or not our actions are actually pushing back against the darkness. I think missions to recover vital pieces of the traveller to raise the amount of light would rock, especially if it were linked to some universal time clock. Making the suggested modifications would certainly make the story and experience much more compelling.
