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

=Lizard=, thank you for the feedback, I think it won't be a problem to consider this option as well – not to penalize it in battle.

In my opinion, the difference between heroes in castles and external taverns is quite logical and diversifies the gameplay.

It breaks the tavern structure, gives 2 extra different heroes, and they come with an army. It seems interesting, but on HL+U with 15-20 castles, 8 players (6x6+2x10=48), 5-7 taverns (10-14), there will be 144-80=64 free heroes left, which reduces variability, especially at the start without heroes. Although this doesn't mean that there will be fewer good heroes, there will still be a negative impression. I'm sure the electorate won't understand.
