That was a big part of Diablo II for me too, maybe I couldn't get the exact item I was looking for but maybe I could find something that I could trade for it. All I needed was something worth 1 SoJ and I'd be set for the trading games until I could get what I was looking for
They should have made the Auction House similar to that of the WoW Auction House. I could not for the life of me understand why they made the D3 AH so unusable and so limiting in features.
That sucks. They should just revise the Auction House system by removing real money trading and not remove it altogether. It just seems weird to play a MMO without a place to sell/buy stuff or compare prices on Auction House/Marketplace.
