The Economy of WoW

[Zarathustra]

Perhaps a repair cost hike for the upper-level items? This way it would only directly affect those using them. The only worry I have with that is the possibility of people hiking up prices to compensate, in which case we're in the same boat we were before. The only difference would be the fact that it's the players' actions causing the price increases, not a surplus of gold.

Guildhouses or personal housing might accomplish the goal if there is a monthly "rent" due, since it would again target the higher-ups. It could effectively remove a good portion of money from the economy.
