If I got a voucher as a nightfall award I would rage! I have no desire to trade any of my exotics. Xur sells armor and with the engrams it's easy after a while to get every piece of exotic armor. This comes down to players wanting a gjallarhorn. Money will start being involved and no way to stop it. Careful what you guys ask for. Bungie will give you what you want. A trading voucher that both parties will need for $19.99 each.
