Improved balance.

While many players appreciate Heroes as a strategy game precisely because of its simple economic model, without unnecessary complications.

Okay, I won't insist. But still, some people will want troop salaries, and those who don't need it shouldn't download the mod (which, by the way, will need to be created separately).

It is a complication, at least because the maintenance costs will not be displayed in the income section of the kingdom overview, and thus, the player will constantly have to calculate and keep this figure in mind when planning ahead.

Out of personal interest, I want to ask: why won't it be displayed? Just curious.

Regarding reducing the number of resources: is this a copy-paste from Heroes 6? That idea didn't work there. And the maintenance complications don't come from resources in general, but specifically from gold (unless resource payments are introduced).

No, I heard that the number of resources was reduced in Heroes 6, but I didn't take the idea from there. But still, I want to say that the resources are somewhat illogical; for example, mercury is needed for building structures. Maybe this is one of those features that have been in Heroes from the very beginning.

Approaching reality is good only as long as it doesn't ruin the gameplay.

I agree with you on this, but I'm not suggesting making Heroes like Victoria. I admit, I didn't understand what troop salaries and game dynamics have to do with each other.
