Kael
Deity
Ah! I misinterpreted. Hum... it fixes micromanagement and makes things easier for the AI, but I do sort of like the system as it is now. Maybe we should let the AI cheat in the way it does with adepts and mana nodes. So long as they have one forge (weaponsmith) and access to copper and/or iron (mithril), they automatically upgrade in cities; however, keep it the way it is for humans.
If the AI has access to copper or iron in a city it will always build a forge there. The thing it doesn't do is pull units back to the city for upgrades.
