I was having an off day today, and got Thingie Manor in the Duty Roulette. The Monk in the party kept running ahead of me, and bringing patrols back to where I was just barely keeping the pull I'd made together and not letting the healer take any aggro. I actually stopped in the hallway and said, "Look, I'm not a good enough tank for what you're doing here, please stop."

The monk laughed and said the healer could heal through it.

It was not the best experience I've had in a dungeon.
