Well, it's for server ops and beta creative anyways. No real reason for any class to get it. Dragoons will be abusers of critical hits, and the effectiveness of that is undetermined as of now. Still holding out for a buff and a rebounding Jump- you hit something on your way down from the Jump, you fly back into the air. Because FF dragoons don't land on their enemies, they return to their spot afterwards.
And actually there were flying dragoons in FFXII: Revenant Wings, but they had angel wings anyways.
Overall, once 1.8 comes, Dragoons in particular will need some love, although I doubt we know how it should work out at the moment. We'll get there when we get there.
