Well, not good for balance maybe. Unless smaller weapons automatically then made for better to hit/parry.

Unless you want a situation where everybody just goes for the biggest weapon possible.

And a 2 handed club doing better impaling than a rapier if both have nica bonnes does sound silly to me. Maybe make so runes see what innate crit types a weapon nhave (not counting materil) and then.. add a lot more if innate. A club getting a lot more crushing than a rapier from malsa xen, and reverse for nica bonnes.
