HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

You are greatly exaggerating the capabilities of quick battles. If we exclude very simple battles, like angels against weak units, the percentage of battles that will yield acceptable results with quick battles will be quite small. The argument about beginners is also strange; it hardly makes sense to try to force someone to learn how to play Heroes. In the World Tree, advanced quick battles have existed for years, and the negative consequences that are being predicted here have not been observed. I also don't understand what advantage quick battles without mana expenditure give over the opponent. So, I fought in a quick battle without losses, but with mana expenditure, and naturally, I replayed it manually without magic, wasting my time and the opponent's time. How will the opponent's interests be harmed if I immediately fight in a quick battle without mana expenditure? And the desire to create one's own "smart" quick battle without "bugs" threatens to isolate its supporters into a separate group, within which such a quick battle will only be played.
