He could be some sort of "attack mage" themed-hero. "Battle Mage", "War Mage", etc.
--EDIT--
I'm agreeing with whoever said he should have a "calling thunder" anim with one hand. That would work well with an actual "Call Thunder" ability. Speaking of which, I'd say that "Call Thunder" would be a simple instant DD-ability with a "thunder" debuff; would that entail neg. armor, silenced, or miss chance? Or perhaps Lightning Shield...
--EDIT--
Hmm... Strength? He
does look thicker, or more armored than his companions. Perhaps then we should
actually make him a more "warrior"-type guy? Perhaps even a melee attack (as weird as that sounds)?
In actuality, I'm adding him solely based on the model/anims; I personally don't prefer anything but the generic elementals (Fire (done) Water (done

) Earth and Wind) for Wc3... Well, that's not exactly true. I love Elementals,
period, but it's harder to see a Lightning Elemental than one of the original 4, see?
Regardless, he's cool enough to just get in.
