The biggest difference between the AI and Human players is that humans actually use magic (i have never seen the AI to use more than 1 or 2 random mages per battle).

As an example, in one of my early MP games, i created an undefeatable army of 200 principes with Pythium and sent them to attack Marignon (or Abysia i forgot which one) and i lost all of them in a battle where the enemy fielded just 10 F2 mages with some bodyguards. (A fireball kills 3 principes per cast, so with 10 mages spamming fireball i lost 30 principes per turn).

The other important thing is that players at least the good ones will adapt themselves to your tactic if you are at war with them, so its not like against the AI where you can field always the same armies and always win.
