@Riot: Suggestion for Blitzcrank's W

So, when Blitzcrank's W was nerfed, the point was supposedly to emphasize his high risk-high reward gameplay—the idea that he shouldn't be able to get away so easily after a failed hook or a botched engage with his E after running at the enemy carry.

Right now his W can't be used as an escape or chasing tool, though. It's also not very reliable for roaming. Those aspects have nothing to do with the high risk-high reward gameplay, yet they have been significantly affected by the added slow to his W.

To maintain the risk he has to take when engaging or trying to throw his Q while also giving him a decent ability to roam, escape, and chase, I think modifying his W like this would be appropriate:

"If Blitzcrank hasn't used an ability other than Overdrive in the last 3 seconds [or 5 seconds, or any other number as deemed suitable for balance] before activating it or during Overdrive's duration, the slow is not triggered at the end of Overdrive."

The movement speed decay would also ensure that his chase potential wasn't oppressive, as he would still be slowed down if he used an ability regardless of whether or not it landed.

Thoughts?
