All traits will be made class-exclusive.
Adjustments will be made so that certain actions will only unleash their full potential when paired with traits belonging to the same class.
This is the only part I don't really like, but it's not a big IMO. I would have preferred this to remain customizable.

The Actions overhaul is only a more level restricted way to do the same thing as the current system, which is fine by me. It simply lessens the advantages of lower level Classes after you obtained a level 50. In the end, you get the same set up as before.

I hope the Specific Ability changes are as promising as this.
