I think Psion should be it’s own class, but making the Psychic Warrior into a Fighter subclass just seems cleaner. Why recreate the wheel? We have a subclass system, we have the Eldritch Knight as a base, do something similar for the Psychic Warrior and be done. It gains all the fighting prowess of the fighter, plus 1/3 of the psionic power of the Psion. I believe that’s really what it was in the first place. MAYBE it was more of a half caster, but besides being granted Psionic powers and power points, the Psychic Warrior was a pure fighter.
So I say any hybrid Psion should just be a subclass. The Pure Psion would be those with abilities that are uniquely Psion, such as the Nomad, the Shaper and the Telepath. Those should be subclasses of a Psion class.
