Having just got Holy recently, I've been wondering how other WHMs are using this (if they are).

I'm guessing you're meant to use it when you're low on MP and in a tight spot but after using it a few times it just doesn't seem all that useful. The damage (considering it uses all your remaining MP) wasn't anything special, even when I tried using it on full MP. I was hitting around 1400 with it on lv48 monsters (at 50CNJ/WHM).

Is there a use for this that I'm missing? I'm just interested in seeing how other people are using the spell.
