I think there should be an Auction House, and/or a trading area or mail system in the game so we can get rid of unwanted stuff to others who want it. Also if this is put in there needs to be a glimmer increase and to be able to trade with marks (crucible/vanguard).
Also if there is a concern on duplicating just add instant auto save to trading.

I forgot to say give it to all systems.
