@Galiant: You don't have a clue what you're talking about if you think the AH was optional for Inferno. [...]
It's definitely optional because the possibility of grinding gear instead of buying it off the AH is still there. Unless your definition of optional is different from mine...the word "optional" has nothing to do with whether you like the alternatives that exist. If you're dying so much that you can't even repair then you'd go grind mobs that you could kill, repair with that gold and grind and gear up where you can without dying so much that you can't repair until you could eventually progress.
I mean I could also theoretically cut my finger off with a spoon if I want to spend a month there sawing at it, but it's so unrealistic to expect it, and there's an alternative so much faster that I'd consider that functionally equivalent to impossible, and so if I were going to talk about cutting my finger off, I'd say it's "not optional" that I need something sharper than a spoon to do it with, because I'm not a total asshat over semantics.
