I definitely miss trash with actual mechanics, like we have in Qarn. The faces have to be killed in certain spots, or the bees have to be burned fast. . .stuff like that. Lost City and TT HM feel like they're trying something similar with the invulnerable mobs, but I don't really count that. I don't consider a kill order to be mechanics.

I think there's an audience out there for a 4-man dungeon with trash complexity equal to or maybe above Qarn's, and boss difficulty like AV. . .
