I read a little bit of all the classes in the book and by far, my favorite class is the kineticist. It is possibly one of my favorite classes in the game. But anyway, when I first skimmed the entry I was surprised to find out that this guy had no spellcasting and his only special thing was his blast attack. Just an idea but: what if the kineticist had some sort of low level spellcasting similar to a ranger or paladin. As in it would only go up to 4th level spells. These spells would probably reflect the elemental focus the character chooses (burning hands-fire, hydraulic push-water, etc.) Again just an idea.
