Discussion about the FORTRESS race – Dwarves.

I don't know about you, but this is what worries me. Runes consume (or don't consume at all) resources. And now the question is: what to do with resources when the castle is built? All races dump them on the market for cheap (except for the mages). And the Dwarves invest them in runes. And unlike the mages, whose bonuses are strictly limited and static (I mean that they cannot be changed during the battle), the Dwarves have a complete imbalance. How to fight a dragon with 3-4 runes or a berserker who is resurrected by runes and tents? And another question: has anyone noticed if the resurrection rune reduces HP or not?
