I build training halls and the hero hall after constructing the capitol. Therefore, I have enough money for training. I only build angel dwellings and recruit angels if I have extra money. In the second mission of the third campaign, Godric had almost as many archers as Marchel had skeletons. Godric fought unappetizing neutral creatures and heroes, while Marchel only fought appetizing neutral creatures. Both reached the maximum level.

Perhaps when playing against humans, a Knight will lose to a Necromancer. I am playing version 1.41.
