Which version of Heroes do you like the most?

Giving it a 10 out of 10 left me with some vague doubts. If everything remained as it was, but a patch 5.0 was released, adding just a few ideas from the 5th installment, it would significantly improve the game. The gameplay, which had become rather monotonous, would be updated, and the standards would change. Of course, many wouldn't accept it, but I'm not suggesting remaking Heroes of Might and Magic III into Heroes of Might and Magic V. Just 2-3 fresh ideas for each faction would be great!

Let me give an example. I've been playing Heroes of Might and Magic V for quite some time, especially versions 1.0 and 2.1. But recently, after trying version 3.0, I realized that a lot has changed. Many new tactics have emerged, and a lot of old ones have disappeared. And despite this, everyone is playing version 3.0. I think that in Heroes of Might and Magic III, fresh ideas would bring diversity, knock the absolute leaders off the top of the rankings, and give newcomers a chance to start on equal footing with everyone else.
