Fists of wind is junk. Race someone that doesn't have it on... it takes a long time to even see a minor difference in speeds. It is not enough to make you dodge plumes. If you have trouble dodging then first of earth is a better choice.. or you could just not stand in bad stuff.

@kaox_reaper... as far as I know its next to nothing. Seems very similar to wows minor run speed which was something like 7%.
