Why, despite having such a (seemingly quite extensive) community, does Heroes 5 still lack a large-scale mod (like, say, HotA) that would address all the key balance and bug issues and add replayability? Seriously, over the past 15 years, a huge number of mods, fixes, overhauls, redraws, and rescripts have been created (with a very high barrier to entry, and undoubtedly requiring hundreds of hours of work), but no one has yet thought to fix the most important thing: balance and bugs. The entire community for the fifth installment, no matter where you look, is either playing the vanilla version, or HotA, or RoE (which are mostly just vanilla with some additions).
Are there any people here who are interested in the balance and mathematics of the original game? Its systematization and structure?

For example, I think that the magic system in Heroes 5 should be changed first and foremost, by tying all spells in the game to the school of magic. This is one of the key ways to increase replayability and variety in the game.
