This probably doesn't count because my combo contains too many jobs, but I once had a party full of these characters--

Lancer with Math skill (maxed out time/white/black/summoner magic skills)

That way, I could hit my enemies no matter what. If the math didn't work out, I could jump all the way across the screen. If the enemy was casting some crazy magic spell, I could jump to hide from it if it was going to be cast within my wait time. XD

Plus, I just love Lancers. They look sooooo cool!
