What do humans, elves, demons, etc., have to do with it?

As I understand it, the idea is to tie an element to a race. I just wanted to separate the damage calculation by elements. I don't see much point in tying it to a Faction – this applies to Chaos, but for example, it’s completely irrelevant for this Knight.

It's not relevant for Humans; both Water and Air are good at low levels (although Air is closer to the lore). But when you consider skill level + high/low magic, it becomes noticeable. When it's disadvantageous for Demons to use Fire, and conversely, advantageous for Undead.

6) Question for Nargott. What final version of the skills wheel do you envision?

My vision of the wheel can be found in the Wargame Edition topic.
Specifically, posts 1 and 2
The full version (not as a wheel) is here

Guardian Angel – Human Special Unit in WGE (although initially Mentor was planned as the SU). There can be no talk of any additional effects in combat (technically). But in WGE, the ability works stronger because there is much less "meat," effectively raising an entire stack. Plus, the hero also learns resurrection. And after each battle, losses are reduced by half (the idea is borrowed from the racial human in G4).
