I agree. Even in the manual for ToE, it states that on Warrior difficulty, the AI has strict limitations on upgrades and the Mage Guild (no higher than level 1).
absd Try playing on Veteran difficulty; the AI doesn't have these limitations, and your starting resources are equal. Also, the AI doesn't attack after 2 months but after 3 weeks, or even sooner. That's where you'll experience the true potential of the Berserk and other Necropolis units. However, I'll emphasize that even on Veteran difficulty, the AI is still far from a real player, as it sometimes manages to lose badly even with superior forces.
Mutare Drakke Read above; I forgot, and I don't know how to fix it. Maybe you can suggest a solution? :)
