Is there a point for Light Armor in Final Fantasy 12?

Obviously any magic based characters would use Mystic Armor, and any tank/melee character should use Heavy armor for the defense and the added strength bonus which will increase their damage. I know Light armor gives a good hit point bonus but that's not better than defense. Besides the strength bonus of Heavy armor is used to calculate damage for almost every weapon type, even weapons like daggers which take speed into account are still more heavily affected by strength.
