Chazar: Giving the Sages 40 reource cost would be a little at odds with the rest of the game. Reource cost on uniits reflect their equipment, heavy armor high resource cost. So while giving Sages a high resource cost might make them somewhat scarcer it would be inconsistent with the other units. So unless you deck out the Sages in some enormously heavy armour or you start to assign resource cost to all mages, perhaps lab flasks etc takes resources that competes with weapon making resources, I do no think it is a particularily good idea.
