Has anyone created a class that's OGC to fill this hole? If so, where could I find it? I'm thinking about reworking the class, but if there's another version somewhere, I'd like to start there first.
Well, I don't know about A class, but Masters of Arms by Second World Simulations (not to be confused with the similarly names recently released Master of Arms book) contains a series of weapons masters of various stripes, each built around a number of weapon maneuvers. The player may select whatever maneuvers he fancies for a list of those available as the character advances.
