And because of the lack of cavarly dwarfs should have more infantry than the other races. Just for balance. In my opinion dwarf military tech tree could go like this.

Tier 1:
Miners

Tier 2:
Miners
Warriors

Tier 3:
Miners
Warriors with +1exp
longbeards (Like warriors but good morale and +1-2 to defence skill, maybe a little better attack)

Tier 4:
Miners
Warrior with +1exp
Longbeards with +1exp
Ironbreakers

etc.

Hammerers could be the generals bodyguard because they actually is it.
Slayers? I don't get a place for them. Could they be in tech tree after or before warriors or should they have their own tech tree? That would replace the cavarly tech tree.

So what do you think?
