Why shouldn't other styles get the same things? What does that add to the game to restrict it to one style?
Now, I could see it if each style had strengths/weaknesses, so that, for example, you were better at parrying and protecting with a shield but did less damage, and better at feigning and distracting with dual wield and did moderate damage, and maybe just do more damage with a 2H, or something like that.
(Looking forward to hearing hysterical tirades about my lack of realism with those specific choices.)
