Education - a questionable skill, as it fuels the fire of rage.
Defense - readiness is also questionable (how do Orcs even use the defense skill? It drains their rage).
Regarding defense, Battle Frenzy fixes this... If an Orc is set to defend, they will lose 50 units of rage during an attack but gain (if Battle Spirit triggers, they gain 75 units). And Battle Spirit (3 skills give +1 for having only Orcs in the army, +1 to 6 from artifacts) triggers in 90% of cases, as I have verified...
