Thanks for the feedback!
For Savant I was inspired by the concept of an idiot savant, "An intellectually disabled person who exhibits extraordinary ability in a highly specialized area, such as mathematics or music." The thought was that these people would be highly talented at combat, despite not necessarily being hugely physical. They are the result of taking a highly mental person, a psionicist, and then focussing their psionic discipline towards combat.
I did intend this to be a psionicist class. There are no published classes (except perhaps in one TA) that give characters the Psionic spheres as Class skills, os Psionic talents as bonus feats - this one does that. You could not take any of the Psionic skills/feats, but then you might as well take a poor Marine/Martial Artist class, which others have done better than this. Do note that they are intended to be as good at ranged weapons as they are at unarmed combat.
I could easily change the saves, I agree that good Fort/Ref makes more sense for a combat class, but I wanted to make this seem more like an intellectual class that would have good Will saves. For instance to get a better Ref save, you can activate the Combat Trance. This is one area I'm probably not fussed about though.
Thanks again for bothering to comment on it!
