What would you change in Heroes of Might and Magic IV?

In my opinion, the worst thing about Heroes 4 is that it differs too much from the previous installments in the series. In reality, the game is excellent, but there are some aspects that I personally didn't find very good. This includes the hero on the battlefield; the idea is interesting, but the hero quickly becomes too powerful and no longer needs an army. Also, too much attention is paid to hero development, which makes the game more like an RPG than a strategy game. And, frankly, the idea of a hero on the battlefield – I've always considered the hero to be more like a commander who stands behind the troops, observing the battle and giving orders. He doesn't need to personally rush into the thick of the fight; imagine, for example, if Napoleon himself rushed into battle.
