"Bringing it back" means making it the top dps spec.
I'm sure that very few people want to be forced to play an absolutely faceroll spec in order to maximize their damage. The more difficult specs should always result in higher damage. (It is impossible to make all three equal)
I would hate for cata to be like pre 3.0.8 BM playing in PVE, everyone would get bored easily, and there would be complaints similar to this one, like, ZOMG BRING MARKS BACK.
