Balance in Heroes 5.

About the Dwarves. In general, their castle seemed to me to be the most expensive; you need to spend a lot of resources on it. Low-level units die like flies; the strength of the Dwarves lies in their high-level units, and this requires a lot of resources, so a quick start is not possible. And their archers are also mediocre. In general, to achieve a good army, they need to be upgraded as much as possible first. Then they will become a threat to everything.
