Red crystal

I'm playing the regular version on the "hero" difficulty. The map is beautifully drawn, with well-developed landscape details, but the proposed scenario is rather depressing. On the one hand, it's not intuitively clear what and where to look for (I couldn't find the shipyard workers), and on the other hand, the player is overwhelmed with waves of enemies. The game isn't built around fighting specific heroes, but rather against the flaws of the artificial intelligence. For example, the first enemy, Naadir, with such a fantastic magic stat, could have wiped out my entire army with four "Ice Bolt" spells (he has that spell) by the second week, but he loses miserably. With the second enemy, an elf with fifty blue archers, the same thing happens – he loses, even though that shouldn't be possible. So, the first question is, why create opponents that are clearly unbeatable? Nothing drops from the attacking enemies, and the number of enemies doesn't decrease, so why bother fighting them? They appear very often, bringing only losses to the main character. He spent almost a month and a half just running, with a procession of four flags trailing behind him. They don't fight each other, for some reason. If it were the opposite, the appearance of new enemies could be understood, but as it is, with their increasing numbers, they will inevitably catch up to the main character. The offer to surrender the Castle doesn't seem even remotely appealing. The number of flags following me won't decrease (2-3), and hiding, using the benefits of the "city portal," and replenishing the army will no longer be possible (and even then, not all neutral creatures can be defeated there). In the end, they cornered the main character in the Castle, and three of them attacked him in one turn: some orc, Miv, and Hafiz. The first two lost, and Hafiz was lucky that he knew "Greater Revenge," and he barely managed to defeat my main character. (And then an assassin pops up: nobody wants to give up the Castle?)
P.S. The fact that the map wasn't tested on all difficulty levels is simply not good.
