Do yourself a favor if you don't already know this. Enable fists of wind, and then mouse over the actual buff on your status bar and read the effects.

Funny how the tool tip for the ability and the buff are different. Specifically, notice how the buff states that you get a bonus to weaponskill recast time.

If this is true, have we parsed this up against fist of fire and determined if it does truly give a reduction in weaponskill time that is comparable to the 5% increased damage from fists??
