You know, if you have THAT MUCH of a problem with it, you could always try to report the player for Obstruction and demand the devs address the concept of the legality of substandard play -- which of course could lead to the legalization of parsers and the like.

Or just kick them. It's an 80 dungeon; they should know by now.
