If there's going to be trading added into destiny, there should be after mission trades and that's it. Say there's 3 people doing nightfall. Person A: suros Person B: last word Person C: Red Death Person A has suros already and person C has red death already, so person A, on the end game review reward page would press X ( ps3) or A (Xbox) and person C would accept trade and they trade the rewards to: Person A: Red Death Person B: last word Person C: suros The layout would have the button to ask trade with the person you wish to. So youre Person A and want to trade with person C, Person A: (you) Person B: friend (Square to trade items) Person C: friend (X to trade items) And same for xbox layout. But outside of end game rewards there wouldn't be trading. Somebody gets a legendary they don't want and you want it? Just press their designated trading button and they press yours to accept and it's done. He gets your reward and you get his. This system would work for crucible or raids too. Just have designated buttons for all 6 of the players. Just an idea if trading should be added. I personally think the game is fine without it but it would be cool to trade end game rewards though. Edit: For 6 person raids or crucible players would have different buttons to trade or be able to move the cursor over a name and press square and trade your item for theirs.
