Is Estinien even in charge of the Dragoons? I don't really recall anything saying the Azure Dragoon is the leader, just the strongest. He doesn't seem like much of a leader at all, and giving control of the Knights Dragoon to whoever the eye happens to choose seems sort of..silly. Strength =/= Ability to lead.

If it worked like that, I think we would be the God Emperor/Empress of The Entire World.
