The W is overpowered at this moment just because of the infinite stacking, thus infinite damage amplification, aswell as the damage increase. Perhaps you should make it just refresh the duration and even nerf the AD ratio, as it stand with the AD of an Assassin (From 350 to 500) the ability would deal up to ~ by itself while being refreshable (and, as it stands, can be amplified).
