As far as the Final Fantasies I've played, there hasn't really been many characters in the series with the odd classes. By odd classes I mean the ones we don;t usually see, something on the terms of Mimic, or mime, a trainer, alchemist, gambler, etc.

Before anyone refers to Rikku as an alchemist, I'm not diminishing the fact that she is one, but what I'm talking about is someone whose primary means of attack and healing is through the use of mixing items. I'm not sure of what Wakka's class is. He focuses on weakening the enemy by inflicting them with status ailments. I would like to see a trainer class, someone who uses captured monsters to battle, but it seems like it might not work though in a turned based FF.

What are some of the minor or forgotten classes in FF that you would like to see return in a specific class format?
