Evolution of "Act Under Pressure"

Hi Mike, question for you:

In the original drafts of MotW, you had Act Under Pressure written like this:
When you are acting under pressure, on a 10+ you do what you set out to. On a 7-9 the Keeper is going to give you a hard choice – you can do it, if you pay the price.

In the final draft, it became much more like AW's act under fire or DW's defy danger, particularly on the 7-9 result.
When you act under pressure, roll +Cool.
On a 10+ you do what you set out to.
On a 7-9 the Keeper is going to give you a worse outcome, hard choice, or price to pay.
On a miss, things go to hell.

So my question is: why the change?  What didn't you like about the first version? Why does the new one work better for you?

Thanks!

That change was a result of the many threads around the place where people were asking "what do I do when I get 7-9 on act under fire?"

I decided that a bit more guidance in the wording was in order.
