Heroes 5.5 WarGame Edition - Tactical Edition.

Yes, I remembered – in the original, both races and skills often have different positions depending on the game time.

Exactly, and this is a fundamental element of any strategy – attacking in the right place and at the right time, which implies different effectiveness of troops/perks at different times and a natural orientation of the balance towards certain timeframes.

It is impossible to fully play a game for 2-3 months that is balanced for 2-3 weeks, and vice versa. To maintain the game on different types of maps, there must be a lot in common between them. For example, in Starcraft, all multiplayer maps have at least 10 hiding places (analogous to cities), a standard number of depletable resources on the base, short distances, and a mandatory presence of ramps (narrow entrances to bases). No one is shouting that the game needs to be balanced for maps played with 1 base, non-depletable resources, without ramps, or with huge distances and a time buffer to "develop, build up to the limit" – all these elements are the basis, optimal conditions on which the game is built.

you need to try – sometimes logic turns out to be useless, because you never know what will ultimately appeal to you, and let it be the most illogical thing :)

That is also true; any decisions may eventually be changed. For example, if it turns out that accumulating troops suddenly has more advantages than disadvantages in a strategic sense.
