Right now Ghost Iron Ore is 4g 46s on Chromaggus Alliance, one of the least populated server pops. It's 2g 8s on Illidan Horde, one of the largest pop servers. Where do you think the price will end up if you combine those 2 AH? It will probably rise a little from 2g 8s, but not much since the Chromaggus Alliance side demand is not that huge. Adding the AH from multiple servers doesn't in any way suggest that the price will drop lower than it is now on the most populated servers.
