Ahem.

Difficulty bad.

Seriously though, why are y'all so opposed to optional difficulty choices in 4 man duties, with normal being the standard for dungeons as they are now? Or maybe the occasional optional (Hard) dungeon, that's actually hard and not just a revisited version of a previous dungeon? It's not like everyone that wants challenging 4 man content wants something on the level of Ultimate, just something that requires a little more thought than "spam aoe on trash, slap mini-boss like a red headed stepchild".
