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

too much attention is paid to hero leveling

And what else do they level up in Heroes?)) The army?:)

And, in fact, the very idea of a hero on the battlefield, I have always considered the hero to be something like a general, a commander who stands behind the troops, observing the battle and giving orders. And he absolutely does not need to rush into the thick of the battle himself; imagine, for example, if Napoleon himself rushed into battle.

If we are comparing the hero to real commanders of the past, then we should compare them to an earlier period, namely from antiquity to the Middle Ages. Of course, not every commander was on the front line, but it was possible to reach almost any commander, and battles were often won by striking at the commander. For example, let's remember Alexander the Great.

In Heroes 4, the battlefield is quite large, and the commander can be either behind the troops or on the front line - it all depends on the player.
