You're wrong! It's not that bad...
The units are quite strong. Only Elven Archers can compare to the bear riders, and you'll agree that the first-level units are powerful. The blade throwers have a great ability – crippling wound, and they are simply indispensable at the beginning of the game (and the lack of ammunition is compensated by the cart). The Lava Dragon is not only the biggest and strongest, but also allows you to use the "through Armageddon" tactic. The Jarls may not be very strong on their own, but when you apply the Rune of Battle Fury to them from the very first turn, they can destroy almost the ENTIRE enemy army!!! The Arcat priests are also useful; they have interesting spells. Berserkers, yes, they are a bit of a letdown. I usually don't buy or build them. But they also have a good use: they move early, they don't have time to kill, you apply the Rune of Energy and activate their ability, the result is decent damage to the enemy, and the opponent will have to finish them off as soon as possible, which means they will waste turns...
In addition to all this, the Dwarves have runic magic and a very good skill wheel.
A strong, worthy race!
