That... actually makes a lot of sense. I don't know how I got under the impression that some aspect of the dragon was necessary for Dragoon abilities. Perhaps I just took the whole Ratatoskr eat-out a little bit to literally?
But seeing as we've seen other Jobs accomplish crazy physical feats with their Aether, it makes sense that Dragoons would be no exception.

Thank you for the quick replies! You've actually cleared up a huge misunderstanding I've had for a year now! ^o^
