For those of you who play Destiny and have reached, say, Level 15 or so, notice that Glimmer, besides its use to buy adequate Uncommon gear and weapons from the class Vanguard, Weaponsmith, and Cryptarch, doesn't have much value beyond that. Sure, you still need it to upgrade weapons and gear, but the higher level characters never seem to worry about how much Glimmer they have.
To get to the point, I would like Bungie to add an Auction House of some sort to the Destiny universe to make the in-game currency actually have some real value to it. Not only will Glimmer be seen as something that is useful, but gear that people find along the way could be sold to other players who are in desperate need for gear. Bungie can add limitations to what gear you can't give away (example: Exotic Bounty weapons), but overall I think all other gear is fair game.
