I checked out this mod, and I have two questions:
1) Why so many heroes? If you do a rough calculation, that's 90 heroes per faction. This means a very long hero selection process and a lengthy loading time for the map settings menu.
2) Why, for example, are there demons who enhance the units of the Stronghold faction, when the Stronghold already has plenty of its own heroes with similar specializations?
Don't get me wrong, I like mods that add new heroes, but in this case, there's a clear lack of thoughtfulness.
And I'm not even mentioning the fact that the white text with the mod's name is very noticeable in the main menu.
