Please, please change Blitz's W nerf.
Blitzcrank wasn't even a contested pick before the W change, and now there's almost no reason to ever use his W, because the exponentially decaying ms buff isn't worth 1.5 seconds of being a sitting duck-golem. Either the ms needs to be flat or decaying less punishingly. If the buff ramped up from his regular ms it might be more fun, and in keeping with "building steam". At the moment it's almost useless for escapes because you can't get far enough away before the debuff, and when you try to us it to engage landing a hook is way harder to position for.
Even though supports like Janna and Thresh will always outshine Blitzcrank competitively for their higher utility, I've loved and mained him since I started playing in late season 2. Please put our beloved golem back on his feet.
