I still have the Final Fantasy I mindset that a standard party should be Fighter/White Mage/Black Mage/ blank, so I always have Zidane, Vivi and Garnet or Eiko, depending on what summons I want at the time. I'll swap out the fourth slot with Steiner or Freya, usually with Steiner more because I like magic sword. I never use Quina or Amarant. Don't like 'em.
