Heroes 5.5 WarGame Edition - Tactical Edition.

I like the idea, but RTA and all its derivatives ruin the strategic aspect of the game. After all, Heroes is primarily a strategy game.
Actually, I had this thought – limit the maximum level of heroes from 40 to 20 – then it will really be the strategic genius of the player that decides, and not an uber-hero, and the role of armies will also increase in comparison to the role of the hero himself. Otherwise, everyone likes to create an uber-hero and then use something called "total clearing".
PS: I anticipate that rotten tomatoes will now be thrown at me:D

I understand that the issue with the high level of the hero can be solved by increasing the amount of experience required to reach the next level, but this is only a partial solution, in my opinion.
