I would go back to an XI style auction house in a heartbeat. Price-fixing is the only main issue I can think of. I know that was a tactic of RMT. They would artificially lower the price on a particular item substantially, so then once the masses started selling at the lower number as well, they would buy them all up and then gouge the crap out of everyone. lol. So again, not bad, just playing the market....but perhaps that's what they were trying to avoid.
