If You Could Pick A Dungeon For A Challenge Mode Remake

[Halifax]

I would love to see some Wrath of the Lich King heroics re-done as challenges.

WotLK heroics were all pretty awesome, but they were ruined by being totally brain dead easy. I honestly can't think of a single one that I didn't think was really cool, if way too easy.

shadow labs or arcatraz!

Black Morass for sure, most of the CM parts of it is already in place it would just need retuning and some new mechanics for the bosses.
