For randomize to make a blog just ASKING for the opinion on whether or not The Duel should come back and/or replace a current game. If there wasn't that "unenroll" button, it never would have flopped in the first place.
RiDsTeR the same thing happened to Survivor a la sjsoccer88's tribe but Survivor isn't being removed. We wouldn't be in EVERY duel and it would force other players to get better or play strategically.
