Dungeons aren't rewarding unless you do them during delves, and once they fix the boss leashing they'll be even less rewarding without running them in a core group of good players.
I have read that the small spiders she spawns heal her for a lot more than the elite adds that spawn, so focusing them down first would make healing less of an issue. I haven't tested this myself since I haven't done the dungeon since the patch.
I too had an issue with the auction house, the item was successfully sold but no AD was in the retrieve item section. Its been four days since i submitted the ticket, and i cannot even access their support section on the website.
