I played and formed an opinion. Here's what I think (purely my opinion). It's impossible to complete the campaigns because a turn is wasted after each battle – there are missions where you need to move quickly. The skill wheel is decent, but it's difficult to get the maximum ability because the amulet is almost impossible to find. Now, I'll talk separately about the skills and their combinations...

Attack. It's strange that to get Battle Fury, you need to take Tactics and Wild Rage. Tactics is fine, but Wild Rage should be for the Elves – it doesn't benefit other factions (or swap them – for example, Tactics, Battle Fury, and if anyone needs it, they can take Wild Rage). Also, the Attacking Warlock is only useful for the Dwarves; the others don't need to take it.

Defense, I think everything is good, only the Defensive Warlock is needed by Dwarves; the others don't need it.

Luck and Leadership suit me personally. All the magic is also good. I have no complaints about Spellcraft and Education. In Machines, I would change the following. I think it's strange to take Brimstone, Catapult, and Fireball (since Fireball is for the Ballista). It would be better to have Ballista, Rapid Fire Ballista, and Fireball. This is my opinion.
Now, specifically about the skills of certain factions...

Knights – everything is done well, but honestly, it would be better to replace Banishment with Prayer, but the one that was there before. It increased attack, defense, leadership, and initiative. It should be available only to Knights.

Mage, Elf, Dwarf, Barbarian, Undead – they are all done wonderfully; I liked it!

For the Demons, I would bring back Hellfire and Tempting Flame, as that was originally their advantage. And for the Necromancers, I would increase their magic, because their advantage is not noticeable. The hero's attack should be higher; otherwise, if there is no magic, it's useless. And please make it so that after a battle, the speed doesn't drop to half but returns to what it was before; otherwise, it's impossible to play the campaign. I have expressed my point of view. I'm interested in your opinion on this.
