I'd say that a lot of what we do is a combination of Aether and Dynamis. The whole point of us being sundered is that as whole beings of such strong Aether, we drowned out Dynamis. Once sundered, we are better able to manipulate the latter, though it's done unconsciously. Something like the Warrior's Berserk state to me is an example of us combining Aether and Dynamis into a form we can use. Which is why we're so strong-- we're not limited to just one form or the other, but combine the two for something greater.
