Well with the new weaponskill checker program that surfaced not too long ago, it will be much easier to confirm whether or not you can obtain WS points in certain situations. Weapons that require points to "break" store the points on the weapon themselves, and the program reads that information (Which is stored into local memory and updates when you zone). With the program, it has been confirmed that you cannot gain points in Dynamis or Campaign.
If that's true, regarding Dynamis, then it must be new. I've broken two weapons in Dynamis (Axe, and Great Katana). I'm 98% sure you can get points in Dynamis. If it turns out I'm wrong about this I'll be extremely surprised.
