tbh, PLD cross class. there not much choice for end game ><

From CNJ,
Cure - not really useful, and it getting worst once you get Stone Skin. lol
Raise - not useable in - combat. so not really an option for End game
Stone Skin - really nice to have, can be useful in various situation. I mostly use it for when DPS got Res, Stone skin give them a decent buffer for their missing HP.
Protect - for solo content mostly. in End game Raid 99% of SCH will pickup Protect from CNJ anyway.

From MRD,
Mercy Stork - Free DPS, Off-GCD
Facture - DPS increase at the cost of more TP consumption.\
Foresight - a nice 20% increase in Defend,
Skull Sunder - Useless lol, PLD has the similar skill call savage Blade. (this skill prolly made for future Job)
Blood Bath - minor Self-Heal and small enmity boost, nice to have.

The thing about PLD is that PLD job is viable on it own, and not relied to much on cross class skill
Unlike WAR, where they Require to have Provoke from PLD.
