The problem I see with the Psychic class is not that it doesn't have any good ideas, but that it has too many. And by trying to put all of them into one class, none of them have the space to feel flushed out.
There is of course slotted casters. The Psychic doesn't get enough slots to feel meaningful. And there is the idea of slotless casters. But the Psychic doesn't get enough unique choices here for that to feel interesting either.
And of course, you need some kind of cool new mechanism to make the class feel even more unique (something you guys have been hitting out of the Park with in P2e). The Psychic has two: the Amp system, and the rage-like forms.
This class should really pick one from each category, and try to flush them out to make them more interesting. What I would do if I were you is to make the Psychic a full slotted caster with the Amp system (turning the amps into something more akin to metamagic, but that take no actions). And take the slotless idea, mix it with the forms, and come up with the best anime inspired kineticist you can.
By doing so, you can take the time to make these separate ideas really shine. Oh, and add a Wis based Psychic, of course. I really want to play my Psychic Monk.
