Players having only 40 space on the marketboard is the problem.
People just want to sell quick and free up space for next items they are farming, and because they dont have it a lot they are going to undercut REALLY HARD.
The fact of SE completely screwing over economy of their game by crafting changes and etc does not help too. Once something new is out its price is only going down as the demand is getting lower and supply is getting higher with more players progressing into the certain spot where the items are crafted and dropped. Its not BDO where devs in this game manages their game economy carefully, making all activities profitable, nope in FFXIV the amount of gil making methods is limited to you either making millions a week or million a month.
FFXIV as the game itself does not handle its economy well, lesser the significance of gil, putting in more and more materials, heavily limiting marketplace for players, and these are results of lvl 80 equipment dropping in price from 1 mil to 50k.
