Nah dude think this through fully. The way this has been nerfed barely affects knife but slaughters D Claw. A nerf that barely affects the strongest user of the talent but dumpstering weaker off meta applications of it is very poorly handled. Its effectiveness is now entirely a function of attack speed. Its effectiveness is heavily skewed towards fast low cleave weapons.
I agree it deserved a nerf but it would have made way more sense to just reduce the cooldown amount per proc down to 1 or even 0.5s. That would have reduced its effectiveness evenly across the board rather than just encourage knife meta for crit builds.
