I'd like Red mage, finish up the original Six, Though in retrospect from earlier comments, I wouldn't mind a Mystic Knight as an MP based Melee fighter. Be a pain substituting a weapon in for using swords of some type ((Though I'd be partial to dual wielding swords and having an attack with eight slashes.)) It'd probably be a Disciple of War though, where RDM can fit in as a Disciple of Magic.
