If you ask me, no matter what anyone says, this was hinted at throughout the show and was not a deus ex machina so much as a bringing together of everything the Avatar has learned.

I predicted there would be a fifth "element" of some kind. This is like the Avatar State, which is a destructive self-defense mechanism. Similarly, this is the flip side of that coin, one also accessible only to Avatars.
