Unicorn Empire

Okay, I completed mission 3 on Recruit difficulty and leveled up my hero to level 26, because there's nothing else to do and I don't want to start over. I started mission 4, and it's cool, interesting, and challenging – just as it should be. BUT. When you meet Arantir and he tells you that he's going to teach you how to raise fallen warriors after a battle, and you follow him, you encounter and defeat a squad sent to stop him (by the way, this squad has an invisible icon; you can only see it on the map as a flag and movement trails, while all other heroes are visible). You lose almost your entire army because it's a strong force, and I don't have the Subjugation skill, which I could have bought in mission 2 (although I bought everything, just not for Balista, but for Varius). You somehow manage to complete it, thinking it's okay. But the raising ability doesn't work! It's not functioning! You meet the Night Witch, and then Alexander and the starting hero (who has been with you since day one and hasn't attacked) appear. And Alexander is buffed, even though he shows average strength; he has only 3 spirits, but he buffs himself 2-3 times before my turn. Is that normal? With 20 units of cavalry. Interesting. In the fort, I tried to fight him, but reinforcements arrived before the fort. If he had 20 cavalry, 23-24 Monarchs, 14 Griffins, and 70 or 80 Swordsmen and Peasants before, then as soon as I entered the fort, he gained +3 Angels and +60 Archers, and yes, he also has the Ballista skill. I don't know how to beat this. And with -10 morale, even though I took a +2 cloak and gathered +2 buffs, it's still not enough. Blindness and Berserk are useless against cavalry with Purification. And without basic magic skills, it's impossible to spam Blindness on the cavalry and still have time to cast Berserk or Subjugation on other units. And yes, at the same time, 3 heroes are coming from the northwest with a solid stack, not weaker than Alexander. And all this attack starts immediately after defeating a STRONG HERO with SIGNIFICANT ARMY LOSSES, without an UPGRADED CASTLE and NO GOLD! The only way to progress here is to re-level up at the end of each mission for the next mission, about which you know absolutely nothing, right? I even laughed at how the "remix" player approaches the game: he first studies everything, reads all the comments, and completes everything on Recruit difficulty, and only then, when he knows everything, he goes and completes the game. He wouldn't have been able to complete the campaign blindly. That's why he couldn't complete the Master campaign; even on Recruit difficulty, he would be overwhelmed, and he has genuinely difficult maps. But never mind, let's get back to him. I won't complete your map; it's not worth it. Your campaign is of average difficulty; anyone can complete it if they know all these nuances. Although, I really liked the beginning, honestly. And I have nothing else to do but complete a mission and then find out in the next mission that all my progress is useless and I need something completely different to complete this mission, and even to START completing it, I need Subjugation. And you only find this out in missions 3-4. Great. Genius author, nothing more to say. It's nonsense. With Subjugation and magic skills with protection, I'll easily complete the campaign and won't even feel it. But only a complete idiot would level up a Knight and a Dwarf in the Darkness faction! Conclusion: the map is raw, there are no hints or notes about the future. You'll only find out what you need to do when you fail. That's it. There was not a single hint about the Darkness faction or leveling up two heroes.
