drothgery has the right of it. Warmage probably owes something to Hackmaster's Battlemage class (Teflon Billy in Knights of the Dinnertable). The criteria for having something on their spell list is, "does it cause damage?" I've seen a couple in play, and they were great for dishing out the magical smackdown, but no matter how much armor you tossed on one, I couldn't see him mixing it up in melee. They also tend to suck when they run into a problem they can't blow up (no fly, no teleport, almost no buffs, etc.)
