Fists of Element abilities on monk used to actually DO that elements damage, so the movement speed was just a bonus back in 1.xx, but now that they have decided that no elemental resistances was a thing, they downgraded it to the barest of bones and it got stuck with just movement speed increased. It used to have a purpose, any mob weak to wind and you would pop that on to do added damage. Now it doesn't have any purpose other than to move faster. "Dumb"ing down things never has sat right with me and this is one instance I really hated how they changed from 1.xx
