How i see it...
4 Man: Protect, Eye for an Eye, Swift Cast are by far the best options. Then you'll likely get Cleric Stance, and Esuna if it is required. Without Esuna, you get one more to pick. (If Divine Seal is still remotely Divine Seal, then that's a mandatory pick anyway)
8 Man: Both Healers will pick Lucid Dream, Swift Cast, Eye for an Eye. One has to take Protect. Depending on dispels requires, 0-2 have to take Esuna, then you'll once again fill with Cleric Stance and other more damage oriented abilities.
So given that you don't have room to even take it, there's hardly any reason to discuss these Rescue.
