Spell casters for each of the races. Not necessarily unique hero types, but rather ranked units whose numbers would effect the power and intensity of the Magic. Along with a catalog of offensive and defensive spells.

I don't see them doing "catalog" of spells ever. It's gonna be upgrades, with special skills, etc. Tho, I could imagine some spellcaster unit, havinglike 3 slots for a spell "upgrade", to have several.
