I don't know what the big deal is. Just don't buy items from the cash AH then. When have you ever "needed" items from other players in Diablo anyway? There will still be a non-cash AH for like-minded players too. If some sucker wants to pay cash for my scrap drops that I get just for playing the game, then so be it. I won't be paying any real money for anything, but to each their own. I fail to see how this makes the game "more grindy" than it would be without the cash AH. If you choose to turn the game into a job, that's your own fault.
