New order.

I played the first mission of the single-player campaign and couldn't complete it. I got stuck at the demon outpost: 57 fire hounds and 15 demonesses easily defeated my 2 Knights, 13 Armored Archers, 20 Archers, and 53 Militia, and my luck (3) didn't affect the enemy. This is not good; the balance is clearly off. Here's what else I didn't like. The experience gained from battles is too low. As a result, wandering around and fighting neutrals to gain experience and skills is a pointless exercise, and that's wrong. The main hero also didn't inspire confidence. Why does a Knight need a Dwarf skill when there are plenty of his own? The proposed leadership skill would be more useful if it were replaced with attack or light magic. In general, in my opinion, the main hero needs to be strengthened at the beginning: it would be good to give him about 40 Snipers, some powerful artifact, and adding Haste to his spellbook wouldn't hurt either. Otherwise, getting through the demons and the monsters on the sides is simply impossible, is it just for show? However, this is just my opinion.

Through trial and error, I finally broke through the first demon outpost, although I was left with almost nothing. So, on the second day, I run into a new outpost - 15 Hell Steeds and 10 Cave Lords, and my main hero has nowhere to replenish his forces. Is this a joke by the author, or is this his idea of how to complete the campaign? In addition to what I wrote above, I'll add that the first mission shouldn't be made into an extreme challenge. No matter what (even if there were no losses), I wouldn't go to the second outpost. Did the author even try it himself?
