Body/Mind Cost and Stamina Deduction are not for you to decide. I know you're mod, but we have to be fair here; you don't rate your own, I don't rate my own, etc.
For your "Pros" feel free to add that it pushes your opponent away (being a blast of wind and all), you can also keep that stun effect. I would recommend removing that bit about a final attack; that won't always be true in all likeliness.
