I have the opposite question... is it possible to somehow restore the AI from previous versions? The thing is, in version 2.1.1, the computer's main hero runs around with a negligible army, while the second, weaker hero, around level 7, sits at the base with a large army. As a result, my hero, level 25-30, easily defeats both of them. In earlier versions, their main hero ran around with a large group, and the weaker heroes simply brought him troops. It's not interesting to fight against a low or insignificant threat... I would like to restore, if not a deadly, then at least a high threat from the enemy heroes!

I think it's impossible to simply restore the old AI without reverting the entire version, so I have to tinker with 2.1.0 (that's what I have). The thing is, this main hero with a small army is supposed to teleport to his Castle as soon as you approach and defend it. But usually, he doesn't do this because his army isn't strong enough to fight back (it should be about 30% larger than yours for him to defend with all his might). As a result, if the computer sees that it can't survive, it tries to run to another weakly defended Castle to capture it, and if there are none, it dies after 7 days. In principle, the AI's actions are correct because if its army isn't much larger, it still won't be able to defeat a smart player... but of course, this reduces the interest for the player in the final, total, epic battle. By the way, if the player's army is much smaller than the AI's army, it immediately runs and defeats the player. In the map editor, by changing some settings, I achieved a more aggressive AI than the game offers on the "Difficult AI" setting, but the lack of cheating with the number of creatures the AI can produce still doesn't allow it to achieve a clear advantage over a player playing at their maximum: saving the game at every step, collecting resources in an ideally rational way, and generally squeezing the maximum efficiency out of the map. Therefore, it turns out that only in Heroes 5 is there a challenging AI, if you add a mod.
