Islands of Mystery, Chapter 2: Dragon Wisdom

I'm very sorry, but it seems that the "Secrets of the Wastes" map in "Hero" mode is simply unplayable. I defeated the Legions of Death; I defeated the Dark Elves, even though they were four times stronger than me; but then, when I encountered the Demons, it turned out that their initiative was always higher (and their hero is level 40, while mine is level 32), and they managed to destroy half of my army before my warriors even had a chance to act. And most importantly, the Imps steal 2/3 of my mana, and no matter what I do, it's impossible to defeat an army that is almost ten times stronger than mine. And it's also impossible to change the course of the game because the army is provided automatically; you can't build it up or strategically outmaneuver a strong opponent (by destroying half of their army with small units and then engaging them yourself, either in the city or at least in a favorable location with obstacles where Chaos warriors can't reach my units on their first turn). Here, everything is just straightforward: you approach the enemy in a strictly defined location, receive your army, and try to win. I almost succeeded once, but I fell just a little short. I apologize if I'm wrong.
