After I unlocked it, my very first run was with 3 other members of my FC. We were all going in completely blind to the mechanics, looking to have fun and figure the dungeon out. It sure was a toughy, but we had a blast nonetheless.

Now, on the note you're probably asking about; my experiences with this dungeon through the duty roulette? Most have been horrible, with runs that take longer than an hour. The dungeon itself is pretty fun, and when everybody knows what they're doing, it's fairly easy. But, most of my experiences with randoms with this dungeon have been bad.
