What about Twitch?

So in patch 4.10 Twitch's Q got gutted.

Here's what happened:

Q - Ambush Time to stealth without taking damage now 1.25 seconds ⇒ 1.5 seconds Maximum time to stealth while taking damage now 3 seconds ⇒ 6 seconds

It may not look like much, but since this nerf Twitch's win rate has gone down to its current 45.25% (according to Champion.gg). How long is 6 seconds? Longer than a Wukong ult. Longer than a Zilean ult. But shorter than a Rengar ult. His Q is now only usable when he is about to go in, not as an escape tool.

Rito plz. Don't buff his other stuff. Fix this. I liked being able to stealth out of a situation. Since this, I die much before that happens.
