[3.P] Masterpiece weapons - Exotic++

[ImperatorK]

I propose creating a new type of weapons - Masterpiece weapons - which are basically what Exotic weapons should have been from the beginning.
Firstly - Masterpiece weapons would all have a decent damage dice. Something like 1d12 minimum or whatever.
Secondly - they all would have nice combat benefits depending on the weapon.
Of course Masterpiece weapons would be extremely hard to wield successfully, so they would require a feat to use (there's no non-proficiency penalties, you either can use it or not). There would also be feat chains or maybe even trees for improving benefits or gaining new ones.

Whatya think?

Alternatives involve making homebrew Martial Disciplines for each such "Exotic++" weapon.

Is this also going to be a rewrite of previous exotic weapons because if you can the Bastard Sword worth a feat I say do it.

I suggest houseruling Martial Weapon Proficiency and Exotic Weapon Proficiency feats to give prof. in all Martial/Exotic weapons, not one per feat.

A nice idea by JackMann from MW:

So, here's an idea. Masterpiece weapons are a subset of masterwork weapons. Ordinary wielders treat them as though they were masterwork. However, people with the right training (i.e. the right feat) can get additional benefits. Greater damage, special weapon abilities that aren't available to the average swordsman. This still gives you weapons that are, in the right hands, much more dangerous, but without having to come up with reasons why other people can't use them. They can. They just can't get the most out of them.
