The devs themselves said they think people can abuse of a cooldown reset. They had the same tought about no cd restriction on changing jobs at safe areas. As for PLD mana, a good PLD can Clemency and use that to raise healer dps or save healer mana on a raid scenario. But these are other topics as their own, I think we're running away from our main topic here. Even though we don't have much more to say.
