If anything I've only seen prices go down. So far by practical measurements all it has done is even out the marketboard prices. If someone is yoinking from a cheap server and selling it expensive on theirs, everyone still has the opportunity to shop on other servers for the cheap price. I made a large portion of gil for about 2 expansions by buying glamour dispelling prisms from a vendor who was literally 30 meters away from a MB and selling them for nearly twice the price. Footwork for profit isn't a new thing.
