I've been playing with 3 friends and we have all been farming Inferno A1 (Jail to Butcher) for a week.
None of us have gotten any drops better than what we have and none of us is able to survive enough to have fun in A2.
A) Progression should not be this bad.
B) The AH is not fun for me. Maybe it's fun for some, but I want to find items from killing monsters (which I haven't), not from scanning a spreadsheet simulator. And part of that is because...
C) The AH interface is horrible. There is no practical way to know what sort of price you should post something for, and not a decently reliable way to even search if you are interested in more than 3 affixes. Blizzard has an AH in WoW and people have built mods to improve its functionality immensely. They explicitly disallowed mods in this game, but released and AH that is horribly unfriendly, yet required to progress. I don't want to spend time doing this.
D) Saying that Inferno is a 'bonus mode,' so we shouldn't complain about it is fundamentally wrong. Your character only reaches level 60 right as Inferno mode is unlocked. By the time you hit 60, you have just beaten Hell and only then are you able to get NV buffs and have all of your skills unlocked. To say that all of the content that occurs once you've unlocked a full build and all of the mechanics is 'bonus content' is a cop out. "The game begins at 60" ought to be true, but instead it's more like: "The poorly thought out boss affixes (invulnerable, cough) and terrible balance (any build is viable! except most of them!) and progression really get highlighted at 60."
F) No Ubers? No anything at 60 or Inferno except for the same acts we've already ran? Really? I know that D2 didn't launch with bonus content at 60, but that game released years ago and the D2 maintenance team supposedly was smart enough to realize that people wanted something new at high level, not just doing the same Baal runs. It's just lazy design that I'm skipping the same cutscenes, running the same content, and there is literally NOTHING to distinguish Inferno from the rest of the game, except the balance is completely wrong.
