First preview is up. Just started looking at it; more details when I've finished.
Looks good so far. Armiger was perhaps not the best choice as a preview class, as grasping the new concepts can be difficult enough, but I muddled through. The fact that the Might-y have a "martial focus" (Basically choosing one sphere effect to get a passive from at a time) makes me want the whoel thing now so I can make a Psychic Warrior archetype that had both kinds of focus. The best analogy for the Athletics sphere is that it's like the Nature sphere: lots of options based around one type of athletics. Sniping was smaller, but I already am planning on how to make an elementalist with this sphere.
So far, so awesome. 'Nuff said.
