Maybe its just me, but i feel like it would make sense for sages to be able to bring labs or Unis into war. Maybe Unis or Labs produce a small amount of resources per acre (for the sage), like 3 gold OR food OR 1 rune per acre. If the labs or unis produced an extra amount of a resource (or all other resources), then a Sage could always have a small amount of labs or unis to supplement overall build plus add a little of their personality's theme. I mean you could just do bonus efficiency on labs, but i feel like that would lead to another age of super sci. Bonus resources produced on science buildings adds a little more color to the playstyle of the sage.
