Level 41 PLD here, I have been using Foresight, which is obviously a solid lock, Bloodbath (which I am using less and less), and I am using Cure A LOT. I know its semi-weak, but on those fights where the healer goes down from an AE with 10% of the bosses HP left, I can pop Coval+Rampart, target myself and spam cure and keep my HP pretty steady on most fights. I sometimes use it to overheal myself for extra enmity, or toss out a 180pt cure to the healer if they take a hit from an AE. All of it is emnity generating, and its all useful. It gives you a second crappy healer when you feel like blasting out about RoH combo is useless.
