My basic set up for my healers is Raise>Curage>Esuna>Cura>Cure>Attack Leaders Target. For everyone else it is basically Raise>Cure>Attack Leaders Target.

If I need to make boss specific adjustments, I do, but that is for general grinding up there. It can be rather mana draining for your healers, so you might want to wait until you get three Mist Charges before you make your gambits so heal-heavy. Esuna can be hard on your MP, but with three Mist Charges its not that big of a deal.
