I actually ended up deleting all my characters after Loot 2.0 came out, right before Reaper of Souls dropped. I really didn't like the AH, and liked even less that I was forced to use it to stay current. I salvaged all the items in my stash, but kept the gems, and obviously the money. While I may not have been able to go back to starting completely pure, I feel like I was able to wash the crap of the AH off. It felt good, and now Diablo 3 is the game I really always wanted.
Did anyone else go through a similar soft reset on their D3 account?
