Are there some job combinations and abilities that you always have in your party, even if it's just because they're cool?

For me, I always have a Wizard/Time Mage combination with Teleport. I'm always partial to black mages, so after he learns enough time magic I will switch the character back to a Wizard. And Teleport may not be the best moving ability, but it just looks so damn cool. There was also one time where I managed to teleport across the entire screen to blow up a last enemy (I was fortunate enough for there to only be a 1-turn wait for the spell), and it was so awesome that I will continue to try stunts like that, despite the ~1% success rate.

I also always have a Ninja/Monk combination for much of the game, which often ends up being Ramza. Ramza to me always is a physical character, despite my preference for magic. I really like the Monk abilities, and the jobs logically just seem to go together from a non-technical perspective.

I often change it up with my party members (though I am partial to custom units instead of the special characters), but those are my mainstays.
