Purely personal impressions:

- Humans - all are equally useful, except for the forgotten crossbowmen;
- Elves - all are equally useful, except for the almost forgotten masters;
- Mages - all are equally useful, except for the obsolete obsidian gargoyles;
- Dwarves - all are equally useful, except for the warriors and Arcat dragons, who clearly outperform their counterparts in terms of parameters and abilities;
- Undead - all are equally useful, except for the banshees, which are significantly less effective than their colleagues;
- Demons - all are equally useful, except for the imps, with their purely situational ability;
- Wood - all are equally useful, except for the nimble riders, with their weak flanking attack;
- Orcs - all are equally useful, except for the blood cyclops, who are inferior to the free orcs in every respect.

Conclusion: there are no ideal races, but dwarves are slightly behind the others.
