Those low prices on the market board...

[Jojoya]

SE has done a good job enabling ignorant/thoughtless players to completely destroy the economy on most servers.

I'm not seeing any economies destroyed. I've still profited quite well so far this patch despite selling many items for less than I did in the past. Perhaps you're focusing on the wrong items to sell or have your per item profit expectations set too high?

For the economies to be destroyed, the majority of items would need to be selling below the sell to vendor prices. While there is a small percentage of items that are that low, most items are still far above it.
