The game desperately needs a listing fee. Every other MMO that I can think of that has a relatively stable economy has one. XIV desperately needs one. Either that or we need to go back to the wonderful "blind pricing+bid system" we had in FFXI.
The market boards are unstable on high end goods because it costs nothing to continually undercut each other. The cost of Taffeta Cloth on Gilgamesh has dropped significantly because of this over the last few days. People continually undercutting each other by a few thousand until someone gets fed up and undercuts by tens of thousands just to get out of the market.
