Fair enough, but 'min/max' players make up the majority of Action RPG gamers from my experience. People for whom it's about the journey (like myself) tend to be in a distinct minority. From the way I've seen the loot system in D3 described at length by many posters in several different threads it seems like the majority of players would be compelled to use the auction house. Call me a cynic, but given that Blizzard is taking a cut of every transaction, that smells like a design decision, not happenstance.
