Too long, too tedious, unrewarding.
Unnecessarily large map, labyrinthine layout.
Lots of trash mobs with large life totals and/or high resistances.
Last boss is a DPS check. 3 bosses that when they reach 1/5 or so life get a shield and start regenerating up to 50%.
Trick is I think only one can have it at a time so you must switch target when your current gets the shield and hope that you can kill him before he gets it himself. Low DPS tank champs are boned as per hidden path spider boss.
You have been warned.

I would rather do 5 times steps of torment than have to do this dungeon once. But hey at least I got my bags full of greens (sarcasm).
