There probably should be additional modifiers for scalability, or the existing modifiers made stronger. Weapons directly add to physical attack skills, while comparatively, the power of a mage's wand or staff has little bearing on the actual spells. That's a portion of the itemization that is worthless to a mage.
Another idea, would be making either intelligence, or weapon damage/quality of a mage weapon, have the added effect of adding some form of spell penetration effect, where the higher the value, the more damage they deal specifically to armor.
