I was part of the crew to go delving into this dungeon.
Bornheld was 31 Warrior going in, came out 32 almost 33.
It was fun, exciting, puzzling at times, but easy to figure out because we seen the vids

.
The fights were confusing to me, for the most part, I felt like one of those little kids that
puts his head down and rushes forward wind-milling his arms just hoping to hit something.
I didn't know if I should ranged or melee, so I was in and out during most fights as my health allowed, this seemed to work best for me, I am spec'ed for Damage more so then defense, and I could watch the adds and help on them as needed better.
All in All I enjoyed myself, the learning curve will be in forgetting things i always knew about playing a warrior in past games and how to crawl a dungeon as though it were straight from a DnD modual as a PnP style dungeon crawl.
Loved it
