Extreme Market Board Undercutting is a Problem. Who ultimately benefits from this?

[Barraind]

Each time i see someone complaining that they dont have money for this minion/mount/crafted item/etc at the market board, that's someone who would have buy it right away if the price was low enough so they can afford it. Thus speeding the sales instead of waiting days, even weeks, for a few selected rich ones to buy your items

Just because someone says they would want to buy X doesnt mean they would actually buy X if you put it on sale for what they might be able to afford.

Items that are sold for significant amounts arent arbitrarily priced, they're based on the price of the mats required or general ignorance (I made a few million gil selling glasses that cost like 3k to make for 100k).

You wont be getting a sephirot tree for "cheap" ever, because fiend sap is the limiting factor. You wont be getting purple trees cheap. you wont be getting most glams that use map-spawned instance drops cheap (or not for several patches).
