Power Break — Inflicts damage and greatly lowers enemy Strength.
Magic Break — Inflicts damage and greatly lowers enemy Magic. Useful against powerful spell casting enemies.
Armor Break — Inflicts damage and greatly lowers enemy Defense. This also nullifies armor on armored enemies which otherwise only Piercing weapons can do normal damage against.
Mental Break — Inflicts damage and greatly lowers enemy Magic Defense.

Why not put Utility on SAM? They have the basis for it.

Focus — Increases the magic and magic defense of all allies, the effect can be stacked up to 5 times.
Reflex — Raises the evasion of all allies, the effect can be stacked up to 5 times.
Drown - Water-elemental spell that deals Water damage over time and lowers an enemy's Strength.
Frost -Ice-elemental spell that deals Ice damage over time and reduces Intelligence stat.

There is a lot of grounds to make BLM have utility too.

This way we can stop the Personal DPS vs Utility DPS fight once and for all.
