Balance in Heroes 5.

I've been reading what people are writing here about balance—my jaw practically hit the floor! Think about it yourself, dwarves are CHEATING! Simply put, their troops are incredibly hardy (don't even argue), their racial abilities are unreally cool—readiness, both herds, pyrokinesis—basically all their abilities are overkill, rune magic in the late game giving insane bonuses (resurrecting 40% of a living stack twice), building costs (for example, 8000 for the capitol instead of the standard 10000), the tower providing absolute invulnerability when fighting in the castle and, as a finale—dragons with unreal attack/defense and 280!!! health. Regarding balance, I can say that it feels like some races were created exclusively for rushing, while others are for the long game (that's what being tailored to specific maps means).
P.S. Demons and necro rule (Deleb, Kaspar and Vladimir are invincible super-wonder friends!)
