Either exchange or sell for an insanely high amount, which is not exactly a market anyway. A masterwork would go for 600k base price, then add in rarity, if you want the fotm masterwork weapon you'll have to pay 1 milion, who the hell has that money anyway, in a few months maybe (the money will be circulating and not being deleted besides upkeep while always increasing so there will be constant inflation). So for now, money would be good for trading other stuff and maybe 1x heirlooms (for 200k), i also wonder how linked it will be to strategus.
