I kind of agree with Falcore.
The server economy needs to be planned from before server is ever open, and number of really desired items should be significantly smaller than number of players. (think like back in a day, there were about 2,5k players per server and only about 50 SSOYs in circulation) Essentially there should be 2 sets of items for any given level range (even lower levels) common items, and rare items. The everyone can obtain common items, but rare items would become something player would seek and trade for. The current gear progression layout pretty much provides any given player with everything his class needs to progress. Economy on other hand is based on a shortage, which then causes demand. I think its not possible to just push THF into "economy" mode without heavy restructuring of gear progression tier and its availability.
