Ideas and suggestions.

The idea of balancing all skills is completely utopian and absurd, in my opinion. It's normal that there are top-tier skills and weaker ones – the game is based on this.

I disagree. In the World Tournament project, for example, despite all its flaws and shortcomings, the skills were quite well balanced, although the implementation wasn't entirely successful from an atmospheric point of view. It is possible to balance and equalize skills; in this example, it was achieved with properties and mysticism (as well as several other skills) simply by adjusting the numbers. So why not do it?

The fact that the game is based on top-tier skills is true only for the current version of the game. Raising weaker skills to an adequate level is more than achievable.

It seems to me that since you've already started working on properties and mysticism, raise them to a reasonable level. Increasing variability and diversity is one of the main goals of the Hota project, as far as I know, so please implement this variability and diversity in the skills.
