I'm concerned as to why the discussion is about PLD holding hate. Do they other classes not use their enmity reduction skills effectively?

Or is it that they have less HP than a WAR?

Either way I would be crusading for PLD to get the ability to parry while holding a shield. A defender like PLD deserves the extra mitigation technique. Also if they can use MRD's foresight and overpower they'd have an opening AoE skill.
