Building the game around the auction house was a bad idea. The earlier games were built around loot. In this game the loot you really want is in the auction house. The stuff you get in the game is largely trash that you need to turn into gold then go buy what you'd hope to see dropped in your game.
It's no fun to stop playing the game all the time to go browse the auction house for hours. And the whole multi day auction ala ebay...that is just laughably stupid.
