I might be. I guess I'll just wait and see how this whole auction house thing pans out in a few days. It's still too early to really tell.
You don't even have to use the AH(RM-or gold) to play the game. Ever.
Diablo 2 had people buying and selling items all the time, it was just under the table. Now its all legit, and there if you want it.
Don't want to use it? Don't use it then.
Loot still drops from mobs like always. NPC's still sell things, you can still buy and sell things. All without the auction house.
Aside from the auction house and online-only drm, which have been mentioned plenty, I've got little interest since it seems to have abandoned a lot of the depth I liked from Diablo 2. You can't set attributes, and skills are simply unlocked at higher levels and can be swapped with other equipped skills whenever you want. So basically, one barbarian is the same as any other, which kills a lot of potential replay value for me.
All it took away was the "everyone follows this one/two best build" things.
You will still have Sword and board barbs, dual wield barbs and 2hander barbs.
Only the WD class is left out, no dual wield for them.
Have you even looked at the skill tree?

Each skill has a added effect runes and so on. Then the passive skills.
