For me it wasn't the auction house that made me loathe to replay the game, it was the lack of character customization. Item choice is purely about HPS and damage reduction, with all other attributes more or less useless, and the ability to customize your skill loadout at will made it so you never invested in a consistent character. Why would you ever roll another character of a class if it's just going to be the exact same thing in the end?
No I may be unusual in this, I played a lot of D2, but never at a very high level. I would come back to it every few months or after a year of not playing it and roll a new character with some different skill tree choices and have a somewhat different experience each time. I never made it to nightmare, never had a level 99 character, but I found the game a lot of fun. D3 is just too much about the end-game for me, there's no journey.
I had a bunch of toons at level 97; the last 3 levels have the same experience requirement as the first 96, so it's a lot of work to get to 99.
The problems with D3 are manifold, but they all, at least to my mind, come back to wanting to monetize gameplay elements when they should've monetized cosmetics. It's like Blizzard/Activision took a big hit of the EA koolaid and forgot how to make good games. It didn't help that they fired all of Blizzard North back in the day...
If you ever meet a Blizzard North developer, ask them about what it was like. It's an incredible, really just incredible, story of how NOT to treat developers.
