If you did not pick up the abilities from Marauder I suggest you do so, they do come in handy. Foresight - Increases defense by 20% for 20 sec. . Bloodbath is always good to top yourself off for a Spirits Within. Giving PLD access to Second Wind however would take away from the Warrior way of tanking which is HP recovery based in a way, while PLD is more damage mitigation.
Though it would be nice if we had more healing potency so that casting Cure was not more or less a waste of a GCD.
