Even then, all you'd need to do is target a Convalescence-Warrior (+40% yay) to an easy 2k shielding on the whole party, 3k if crit. The other strange thing is that it's basically the same as Sacred Prism (1.0) + Stoneskin. I'll admit I'm more fond of this than that, but both seem kind of awkward. Basically a double-strength Succor if the party stacks, once per <CD>.
The Eye for an Eye effect seems both reasonable and... lackluster. Basically just asks your tanks to be in range of each other each time the SCH, rather than the SMN, AST, BLM, or WHM, would cast EfaE. No one else, hopefully, will be under fire from enemy attacks long enough to proc it.
