Heroes 5.5 WarGame Edition - Tactical Edition.

I would still make three wheels:
the first - general skills (12);
the second - general skills, but for Orcs (12);
the third - racial skills (8)

That's also a possibility.

I'll share another idea regarding the game's economy.

The goal is to significantly increase the value of resources, in addition to gold. To the point where 1 gem costs 500 gold (like on the market), and has that value (currently, the value of 1 gem is around 200 gold).

In essence, resources are presented as the foundation for building cities, while gold is primarily for hiring units.

The total cost of building a city in terms of gold is proposed to be reduced by 10 times (!), and in terms of resources - by 2.5 times. However, the amount of resources obtained from resource piles will be reduced by 3 times (for example, giving exactly 1 gem instead of 2-4), and gold - by 1.5 times (instead of 500-1000, give exactly 500). What will these manipulations achieve? The strategic role of mines will significantly increase, despite the accelerated game dynamics.

Thus, players will need resources to maximize the development of production capacity (building a base), and gold to hire troops. For example, building a dragon lair could cost 1500-2000 gold (not counting resources), while buying even 1 dragon is more expensive (2500 gold + 1 gem).

It is clear that with this model, troops will be bought daily, and not just accumulated, as is the case when building also requires a lot of gold. And this will lead to more active use of troops on the map. In addition, unpurchased reinforcements at the end of the week will be lost, encouraging players to maximize the use of both resources and gold during the week.
