I did it last night. It's an awesome quest and the most GOOD lore I've seen in years edit: although, i did miss the shadowed being and such at the end. It might have been because it was ~6AM and i had to get up in a few hours though
I was disappointed in this quest. I really enjoyed doing it on my zerker but not so much on the monk. I woulda just like to have seen more action than just sparring partners basically. But I do think the devs did a good job on the lore and stuff.
