Putting more thought into Psionic subclasses of Paladin, Ranger and Druid.
While one suggested they take the Divine Mind concept and put it in as the Paladin subclass, I always had the idea for an Oath of Madness/Fractured Reality that was generally tilted towards the Chaotic Neutral alignment, which was a Paladin whose Oath is about their own perception of reality that is different from the baseline reality of others, whether it was the result of trauma, dissociative disorders, the Far Realm, the Region of Dreams or knowing some sort of unknowable truth. It would probably be more slanted to telepathy as it's part of their oath to have others accept their version of reality, such as being recognized as the Princess of Imaginaria, all living things are masses of crawling worms or the fact that their murdered family is still very much alive.
The Ranger subclass could be about hunting bounties with psychometry which is the ability to read psychic imprints on objects and using some psychoportation related powers. In many ways they'd be the ulimate bounty hunters as they can use other senses to track their targets. Some of them might be aberration hunters, or hunters of shapeshifters tracking hidden threats that embed themselves deep inside civilization. Any many ways they could be the actual Urban Rangers that a few have expressed a want for.
The Druid might be the hardest one to fit in a psionic subclass, but there's certainly some sort of overlap between wildshape and many of the body control abilities of psionics, especially 3e psionics where there's many partial shape-shifting abilities such as growing claws and spitting acid. Perhaps the circle will be about an idealized primal beast of many forms, becoming like it in body and mind.
