Phoenix Vision – a comprehensive modification of the game’s visual aspects.

Well, I don't know, it seems to me that this justification is a bit far-fetched. Demons also use weapons quite successfully; Pit Fiends and Devils can attest to that.

Nevertheless, "brutality" is clearly the word to describe the Orc upgrade (the part about demons is just to explain why they are brutal even compared to other Orcs; the demons themselves are more about monstrosity).

By the way, has anyone noticed that the Daughters of the Sky use the exact same attack animation as the Shaman/Daughters of the Earth, i.e., they attack as if they should have daggers in their hands, but they don't...

Not that we haven't noticed, but rather we tactfully kept quiet about it... (or do you suddenly have an alternative??)

The same goes for the changes to Necropolis. I've reworked practically all the creatures of this Faction; in my opinion, it turned out quite harmoniously, but I'm almost certain that many won't be able to accept the fact that pink undead no longer exists.

Well, it's a pity that we won't see purple vampires in your version, but the creature lines themselves are excellent!!! But since you're asking for criticism, please - Necropolis has caught the Haven disease, when there are such contrasting color schemes (red and blue) in the castle that it makes me feel uncomfortable inside when they are present in the army at the same time. This is especially noticeable on the skeletons, and I like to take both upgrades into the army at the same time(((

Regarding the similarity of upgrades - although the concept is not bad and is confirmed in most cases, where not all three creatures are exactly the same, there are also examples where it is unclear whether something needs to be changed - the same Warmongers, Battle Mages, Cyclops
