If a game lacks balance, that doesn't mean a more experienced player cannot win in it. Heroes is a game where you cannot win every match in a row, even if you are stronger than your opponents. A game with this many random factors cannot be balanced. For comfortable play, it is enough to remove imbalanced elements whose arrival completely breaks the game (Diplomacy, Cloak of the Undead King, etc.)

Heroes is a game of distance, and the whole problem is that with such a long game duration, it is very difficult to accumulate enough distance.

This is a dispute over terms.
When playing a coin toss, no amount of experience will help; I call such games random.
It depends on what you mean by "balance." If you mean perfect balance, then only a tug-of-war comes to mind, or something like that. In most games, reliably identifying the strongest player requires some degree of distance. Yes, in Heroes this distance is relatively large, but what follows from that? Should we not even try to shorten it, in your opinion? It seems not, we should, since you approve of removing the Cloak of the Undead King and Diplomacy. "For comfortable play"? What does comfort have to do with it? Some people find tossing a coin comfortable and even fun, others play anarchy with the Cloak of the Undead King and such (some, let's not point fingers, even force this nonsense into official tournaments :)), so they were removed precisely for balance, not for comfort.
In short, I see clear contradictions in your statements.
