[Chaos]

Martial Training is outright busted. Use of Heavy Armor and SAN can grant the Dwarf up to +18~20 Power, which is nothing short of a stellar (passive) damage boost for only a body equipment restriction and points into a stat that compliments their tank-oriented racial stats. (A Sword/Spear/Axe made of metal won't be an issue, since 99% of them use metal anyways)

I'd just put the BW/Encumbrance bonus on Stout Body, and replace Martial Training with something else. Say, an effect that bolsters whatever Dwarves make via Blacksmithing.

Otherwise, the suggestion looks good.
