Has RIOT mentioned anything about tweaking Blitzcrank's recent W changes?

The overwhelming consensus of the community both here and on Reddit is that the recent changes to Blitzcrank's W were horrible and likely went untested before their introduction. For those who do not know, Blitzcrank's W speeds him up, and while it used to be a pretty good speed boost it was spammable and honestly probably wasn't healthy as it was. However, now with the changes his W speeds him up a much higher percentage, but for a shorter period of time, and it decays at such an alarming rate that it now only lasts around 2 seconds compared to the officially stated 5 second duration. To make things worse, it applies a 30% self-slow for 1.5 seconds after it wears off. That's right, it massively slows himself for 1.5 seconds after what amounts to a short and clumsy speed boost. It's at the point where it's very largely unusable.

So, has RIOT said anything about changes/tweaks to this skill?
