I would like the propose allowing the following to be used, to allow Finessers additional options in the weapons they can use.
Aldori Dueling Sword: A finessable longsword that requires Exotic Weapon Proficiency to be used, but would provide Finessers a source of slashing damage that is an appealing option compared to Rapier.
Aldori Dueling Mastery: A feat that primarily is served by the fact that it would give Duelists a source of Slashing damage, it also provides an initiative boost and a benefit for not having anything in your other hand.
