I have sword bands - they have swords bands. But I field 2x the amount of men (as Iceni vs Brigandes). My units are losing, so I take a regiment of sword bands and rear end attack the enemy. They are encircled, and STILL don't flee and I'm losing.
Does the AI cheat in very hard difficulty? Do they have hidden bonuses I can't see? Why is it that I lose vs farmer levy when I have sword bands AND I constantly flank the enemy with cavalry?
