All questions regarding mapmaking for Heroes of Might and Magic 3: The Shadow of Death.

The main hero is usually (but not always) the strongest warrior, the one who captures new castles, objects, and fights enemies... Usually, again, he is determined by the mapmaker at the start, and the player recruits the rest "to taste."

I've never encountered this... And how is it indicated in the game? At the start, everyone usually has the same strength and skills. If the initial hero needs to be protected according to the conditions, then he develops, usually slower, although this might be a mistaken strategy.
Okay, it seems I won't get an answer to my question. I'll finish it as is.
