A stack of re-agents that might sell for 20 silver in Orgrimmar might go for more than a gold in Ironforge; enchantments are far more expensive when bought from Alliance players, and although the NPC goods & services cost the same for the two factions, the inflation on the eastern continent makes for a very different playing experience on the side of the Alliance.
The question is: why the big price hikes?
So, what's the answer? I don't have a clue...what am I, an economist? I'm just a guy who's tired of shelling out my entire days' hard earned play-money to buy ingredients for my recipes from some Night Elf charging me out my Dwarven wazoo for something that my Orc could buy in Orgrimmar for 1/10 the price.If nothing else, maybe this can be a selling point for more players to migrate over to the Horde: "Join us! We're ugly AND cheap!"
