There's a reason I don't like Hell or the new dragon lairs much at all, and that's because you need a group.

Even if I hated that god damn ST for killing me and not really giving me any of the REALLY cool stuff despite my efforts, I still kept going back because it was something I could do on my own, without greedy people breathing down my neck and disturbing me with their near-OOC chatter which is what group exploring with more than 2 people seems to always be like.
