Dear author! I have a question - what is the purpose of this upgrade for the main hero with the red faction??? For example, I don't like the red griffins, monks, and angels at all. And here's what happens - in the city, I recruit the second tier of troops into my army, approach the desired location, and suddenly all the creatures in the hero's army have been retrained! If there weren't two types of armies in the city, this feature would make sense, but as it is.... The player should have a choice of army - I want the second tier, I take them. I want the third tier, please. Otherwise, there's some kind of contradiction - it seems like there are two types of armies, but in reality... But otherwise, it's enjoyable to play on the map, it's good. Good luck to the author and new ideas!!!!

I completed the map in 95 days (hero). The map worked normally: no freezes, no crashes, and at the end, I was given a table with an entry in the Hall of Fame. Good job. In my opinion, the quests are excessively complex, and the scenario lacks dynamics. (The latter largely stems from the former). The main hero is a logistics specialist, but you have to spend a very long time hanging around near the Castle. Grethem, as a starting hero, didn't appeal to me because of the transformation of his troops into the "red" tier. In the tavern, I took Rutger, he cleared the area around the Castle, and then Grethem went on a foreign tour.
The demons couldn't break through the garrison, neither the first nor the second. The first time, the orcs deliberately defeated the guards. The second time, they wanted to repeat it, but they were afraid of my hero and retreated.
Grethem broke through the demon outposts, and the orcs, overjoyed, captured the demon Castle. I watched a cartoon where Knights die while storming the Castle, and was surprised. The orcs declared war on the Knights, although it's unclear where Grethem managed to kill even one barbarian hero. Not for long, the map finally "came to life." During the five-day war, Rutger and Grethem destroyed all the barbarians.
I don't understand why the gremlins with golems joined (another "long-lasting" quest?). I picked up the latniks ("volunteer squad"), but the Rebel Garrison didn't want to interact with my heroes in any way. I didn't remove the curse and didn't even think about it; Grethem fought perfectly well without magic.
I agree with the opinion already written, the landscape could have been drawn more interestingly. The huge territory of the orcs is made very boring.
