Go holy shock! Holy fire rots like a turd in the desert, but Holy Shock ain't so bad! 
So, how is it? Last I experimented with it was, um, when it did 1-3 damage at slvl 1. Needless to say I was quite... underwhelmed... by its awe and majesty. Hmm, I wonder if Vengeance would work super-effectively with Holy Shock. It'd be a fun little elemental theme, but I think most folks tend to go Vengeance/Conviction. Zeal mimics lightning-fast electric currents, so that's pretty cool, too.
*BZZT!*
