Well, there are ways to counter them. The strength of the Northern Clans is offset by initiative. It's offset by magic. It's offset by high attack. Runes don't help either. This has been tested repeatedly.

P.S. By the way, the word "race" is spelled with one "s". The word "rassist" looks strange, don't you think?

I agree that you can find a counter to any race, but the counter to the Northern Clans is... impressive! They still seem stronger than the others due to the combination of rune magic + some other magic (especially light and dark magic helps). And on top of all these advantages, there are the most powerful lava dragons, Arcata priests with their fire wall, and especially impressive are the hundreds of dwarves defending the city, as I already mentioned. No other race has such significant advantages. Unless you consider the human ability to advance to the next level. But this pleasure is unpleasantly expensive. The Undead, with their vampirism, plague, curses, hordes of skeletons, and other nastiness, are still somewhat weak. The battle cries of the barbarians are a good thing, but by the time the creatures reach that 3rd level of fury, more than half of the battle will have passed. And the fact that orcs don't learn magic at all is their main disadvantage.
