Believe me, any reasonably competent commander, at a certain level of military technology development, would sit on a hill and, observing the battle, give orders to the troops. And this isn't outrageous; it's simply foolish to allow oneself to die from a random bullet/arrow (Napoleon, Kutuzov, for example; if either of them had died in the middle of the war for no reason, we would be living in a different world).

Well, it's a "Heroes" game, and heroes are heroes everywhere:D But I agree with you about the lack of competent commanders, but in battle, all soldiers are important! And it's simply necessary to get to the hero, because if a unit doesn't have a general, that's already a defeat. And in Heroes 3, you can't even get to the hero. And I was also annoyed that the units can't move. Why? They're not chained to their generals! (For example, for scouting). One unit can do the same job as a hero who is used for scouting. And losing a scout unit won't be as painful as losing a hero.
