Oh yes, comrade Columbus! Thank goodness you wrote. No one was trying to fix the balance, and no one was fixing bugs – everyone was just messing around with some nonsense! But now, under your banner, we will make the eighth installment of Heroes!

1. Under ideal balance conditions, it's always a draw. Even in chess, the balance isn't ideal, and the number of possible outcomes is minuscule compared to Heroes. Therefore, balance is always a subjective thing. Everyone, with a smart look, declares: "Well, OBJECTIVELY, this unit needs +2 to its attack," – but that's their opinion, and others have different ones. That's why there isn't one great mod. The development vectors are similar, but the modules of those vectors are different.
For this, by the way, I greatly respect comrade Nargott, who makes truly balanced changes, where even a mathematician's perspective suggests: it looks good! And moreover, he explains all his changes extensively and meaningfully.
2. Fixing bugs is a very laborious task. There are no source codes, and the code itself is not fully understood. Nevertheless, many bugs have been fixed.
