Just to give my 2 cents on the Real Money Auction House. Its an option for people who don't have time to spend on the game. In the case of some people, its more profitable for them to spend their time working than playing and trying to get an uber item. Doesnt really concern me as it actually helps me if I get to group with someone with godly gear. Makes killing monster faster. You will get probably crushed by someone i godly gear in PVP. And someone will always work towards being the first one to finish the game in Inferno Mode. Not that I really care since its not an MMO. You finish the game in normal and you know the story and it just becomes a hunt for better items.
