Sage:
~ Tools Science (@130%) multiplies with racial BE bonus (115%) for incredible BE and optimal use of your lands (73.5% BE with 0 Peasants @ 100 BpA Tools, 130% BE with optimal workers)
~ Free land management frees up a lot of spare cash that can be put into Sciences (or military)
~ 145 BpA in War Science matches Orc's +20% Gains
~ 145 BpA in Alchemy Science matches Merchant's Income bonus (in addition to super-efficient Banks)
~ The increased effect of Housing Science enables you to run a large military without sacrificing BE - getting far more mods from TGs, Rax, Forts, and Hospitals.

Warrior:
~ Extra General for an additional +3% OME or attack
~ The +15% OME in War matches a Count War Hero
~ These extra OME mods multiply with TGs (at above-average BE) to match a non-Warrior Orc with a similar build

Cleric is more defensive than anything else. With the higher BE (particularly with Sage) and a few Hospitals, the only thing you'd gain with Cleric would be the permanent Animate Dead effect.


In a coordinated Kingdom, Warrior would win hands-down. In a ghetto, Sage becomes the better option as it's more self-reliant.
