it is not boring playing with 4 fighters... just expensive. Plus, you'd be just as well off with say, 2 fighters... seriously. I say 2 because twice the exp, half the price, and you don't have to worry about one guy getting stunned forever. Then when you make them knights, they both know cure.
Though best party ever, and fastest/easiest game is fighter, fighter, red mage, red mage.
