While they're at it, I wish they'd also allow Ancient Currency (especially Dynamis, but also Limbus) to be sold on the Auction House. Its really annoying to have to bazaar it, because its not realistic for me to leave my computer on and logged in 24-7. Back when endgame stuff was super rare and elite, I could see it making sense but now its just annoying to have to afk a mule while I sleep/work.
My god, there'd probably be more people selling it than people selling crystals. It'd be a realm of undercutters.
