Roles need to be changed to better reflect the game.

When I get into battles in other final fantasy games, when no healing is needed I make my healers attack enemies. No point in just letting them stand there and do nothing.

I usually make them defend because they have low defense and I'd rather not waste time healing a healer or risk them getting killed.

EDIT: Or I have them use support skills. You know, because they're a support class.
