Just a couple minor things I was thinking of adding to the fighter. This first one I think would be a starting move; it's pretty minor, but I thinks helps to give the fighter a little character:

Walking Murder Machine
When you attack someone, armed or not, you always inflict your class damage die.

This next one would be an advanced move, still undecided whether it's 2-5 or 6-10:

When All You've Got's a Hammer...
... everything starts looking like a nail. As long as you've got your signature weapon, Hack & Slash is always a viable move for you. Intangible spirits, giant rock monsters, the Apocalypse Dragon its-goddamn-self; you can kill them all.

(Alternate name: "As God is my witness, I will suplex that dragon.")
