Really, isn't this the best party?
You've got three powerhouses in the front, and in the back there's this jack-of-all-trades guy who can throw most good spells in the game AND attack.
You basically got four fighters, a white mage and a black mage.
Besides, the attack power will get rid of most enemies in the game, and once you've got the best swords in the game, you WILL be unstoppable!
