To expand a bit on @Mecheon's answer:Trying to catch up on this thread, but can someone tell me what the last 'official' version of the psionic was? 3e?
Psionics in 4e were actually spread between four classes: Psion (controller), Ardent (leader), Battlemind (defender), and Monk (striker).
Psionics in 3e were spread between about four classes as well: Psion, Wilder, Psychic Warrior, and Soulknife.
Dreamscarred Press took the 3e classes, balanced them for PF1, and then added additional psionic classes: Aegis (ectoplasmic armorer), Cryptic (psychic warlock/rogue), Dread (psychic fearmonger), Marksman (psionic "arcane" archer), Tactician (psionic warlord), and Vitalist (psionic healer).
