They are actually improving Diablo 3. A big patch came out last month adding even more positive improvements imo. Uniques/Sets matter again. They've come up with a way to deal with special powers they give with their new cube recipes. No auction house anymore, items can't be traded/given away except to people in the game when it dropped and only within 2 hours. So you can play with friends, share loot, but there's no secondary market. They also added greater rifts which allow you to push the end game difficulty indefinitely along with paragon level, which gives infinite 'leveling' via stat bonuses.
