AI in Might & Magic: Heroes VI

Maybe he's just a better player?

How much better does someone have to be to have a level 5 hero defeat a hundred elementals, all positioned behind walls and shooting from there? I remind you, the threat was DEADLY even for my hero. The computer's army was purely symbolic. He didn't have many artifacts – it was the beginning of the game, after all. No dynasty weapon would have saved him either. Just play with an ally and you'll see that things aren't so simple in this faraway kingdom.
