At least someone shares my opinions. I play Str Wars The old Republic in addition to destiny and there we have the galactic trade network (gtn). With it, we can put an item for sale, to be seen by any player, and we put our price on it (in credits). The item is returned to us after a couple days if it was not sold. Taking your ideas and adding them to something like this would prove extremely helpful. It's because of the gtn that my low keel characters have powerful modified gear (for their level). Trading systems would be a great addition to this game!!!
