I guess I have a higher expectation for working content than you do. My surprise isn't that a low priority task isn't getting done (ignoring the fact that nobody from ArenaNet has stated what its priority is), it's that it would be given such a low priority in the first place, and that the best course of action is to remove it as a daily rather than fix it. It's even more surprising when you consider that entry into the mini-dungeon is hidden behind an achievement that the player can't possibly know about without looking it up (which is probably a good argument for it not being a daily in the first place). Therefore you can spend half an hour or more just getting to the final room just to find out it's bugged and to give up. It's not a good look for a game that is relatively bug-free.
