Haven vs. Fortress (how to play against dwarves?!)

One of these is me. I advise you to try to be a little bolder on a large map. If you develop normally from the very beginning (build a capitol as quickly as possible, because the map is large). Since the map is large, there will be a whole bunch of unnecessary artifacts that can be sold, and you will meet Ellaina in the tavern (+2 gold for each peasant).
Imagine a day at the end of the week - 20 cavalry units are prepared, the next day - another 20. (of course, this is not in the first and second weeks, but still, 40 units in 2 days is cool).

It's funny to think that you need a lot of extra cavalry to defeat spear masters. Believe me, in one turn, Isabelle's knights, led by Axel, destroy 2 squads of dwarves (any, but it's better to leave lava dragons for last).

Regarding construction, I'll note that I'm not a newbie in this game, and playing on the highest difficulty requires prioritizing building up your economy, and then everything else. Even with a gold mine (which doesn't appear right away, and the troops on the map are still at the second-to-last difficulty level, and the mine is guarded, for example, by a horde of archangels in the first week), well, never mind, unnecessary artifacts are always sold. And there is barely enough money to buy all the troops. And to defeat 450 spear masters (at level 28, the hero will already have +14 to attack and +14 to defense) in one hit, you need about 200-300 cavalry units, and the opponent is not stupid, they will put defense in front of the spear masters. Well, the cavalry will destroy one squad in one hit, then the dwarves will start moving, the rune of etherealness will be on the first one to attack, then they will all attack the cavalry and, as a result, defeat them with double attacks, and they can also stun the cavalry, and then they will also disrupt the initiative, and I suspect that there will be no money left for other troops besides cavalry. But in general, just for fun, I will try to develop a hero for the humans in this way. But in general, the question remains about the balance in the game. After all, all races should be approximately equal, but it turns out that this is not the case.
