PLD probably only needs some quality of life adjustments regarding stance dancing, a way to restore TP when Offtanking which DRK also needs, and some way around the huge DPS penalty from Shield Oath. Given the current raid design PLD's safety net has kinda become less useful. They probably tried to address the latter with Divine Veil (a good skill) and Clemency, which turned out to be a bit of a misfire since there's a bunch of things that work together to make it a relatively poor skill.
