What does dogma have to do with it? What about standards? A hero-gnome with Chaos and Sorcery will always be more effective at casting spells than a hero-gnome without Sorcery.

And what about siege engines? Perhaps only on small maps. Gnomes have the lowest damage from a ballista.

Why not defense with a strategy of fighting to the last - in my opinion, this is the foundation of victories for the Fortress faction, along with the resurrection rune.

And what about leadership? Rune Harmony is a very effective skill.
