So what are some of the ways you implement "jobs" in FF games where they don't exist?

[Laddy]

I pretty much only did that in FFVII.

Cloud-Green Mage (More of a fighter, but used status spells.)
Aeris-Black Mage
Tifa-Thief
Barret-Warrior
Red XIII-Red Mage
Cid-Dragoon
Cait Sith-Blue Mage
Vincent-White Mage/Summoner
Yuffie-Monk

I really like this setup. I'm gonna give it a try when I replay VII. However, Yuffie should be the Thief and Tifa is actually the Monk

You're right! I switch!
