They can give PLD all the defense, the tippy top defense, greatest defense ever seen, and it won't help without them creating content that needs that defense. At which point, the weaker OT is out. Without that change, even huge defense won't help PLD very much. Unless they get so much defense that the healers can full time Cleric's.

With the current content style, PLD loses out on personal DPS and nothing to boost raid DPS. Which sadly, since I like PLD more than WAR, makes them the loser in many people's views.
