Please keep in mind when reading this that when it comes to topics relating to economy, I'm useless.
Which is why I'm asking you more educated-in-economical-stuff people this question:
How good or bad would one auction house for all realms be?
I mean one for all NA realms, one for all EU realms, etc.
I don't want to see things like "it would be really hard to make" or "the technological complications would be too great". I want people to reply to this and say why this would be good or bad for the economy of the World of Warcraft.
