SCH even better!

[Shurrikhan]

I think the effect of it only refers to spreading the shield from Adloquium to nearby players, not the actual healing, since that takes place when the spell is cast while I'm guessing Deployment Tactics works like Bane but on beneficial effects. I too wasn't sure though, which is why in my post above I put "heal/shielding". Still, the more I think on it, the more likely this seems to be the case. Otherwise why announce a new AoE healing spell as well?

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.
