I played for a while and gave up.
I understand, it's supposed to be hardcore, but... everything needs to be in moderation.

I've been playing the second mission for a week now. I've reached the battle with Kha-Beleth.
Can someone please explain what the point is?

What's the point of this meat that just multiplies during the battle?
What's the point of spending months building up your army and just defending against knight attacks on your castles, only to have Kha-Beleth's meat multiply in proportion to yours, making your chances of winning minimal?
What's the point of suffering when playing as a Warrior?
What's the point of this idiocy?

What was the author's intention? To show how mega-hardcore he is? To make the player nervous?
I've always believed that a game should be enjoyable. But when you spend hours, try different strategies for weeks, and just get frustrated because you can't beat a map, that's wrong.

There are Veteran and Hero difficulties for hardcore fans.
Why put legions of armies on Recruit and Warrior difficulties? Why can't you play the Master maps in a relaxed mode?

I don't understand. I like the map design and the author's idea. But these hordes of meat just ruin the whole experience.
I can't say anything good about it.
