Re: What are you playing right now?
I looked through some articles on the issues with the auction house and it's got some fairly extreme negative feedback. But apart from all the usual whining about micro-transactions and greedy companies, it seems the real complaint is with the drop rate of decent loot. The overall resentment towards the auction house is based on the fact that rare/legendary loot drops are so poor, it's the only realistic way to get playable gear for the harder difficulties.
That's a shame but I'd hardly say the AH is to blame. Blizzard could patch the drop rates easily enough and that would make the AH just a quick alternative but still leave the excitement for those that want to properly explore.
