The Warriors and their weapons - "Thats not a knife, THIS is a knife"

[TJS]

I think a compromise could be simply to increase the damage dice rolled for heavier weapons to make up for the lack of blows per turn. So a lead-filled mace could be 5d8 or something like that. This might make some of the slays more useful for heavier weapons as well.

Also perhaps increase the frequency and effectiveness of critical blows too.

Weapons could decrease enemies AC by their weight when attacking.
