@solcrushed, Idea for gragas W

SO was playing grag a little more today and had a bit of inspiration with his W. It is not a very satisfying skill atm. There is no clear time to really use it and it is essentially placing you into stasis until it is over. If it gets interupted you feel like you cant contribute fully in a fight as your damage is severely reduced without the bonus spell effect.

The idea I have is this, instead of having the bonus spell if you successfully complete the drink duration, have it scale in power with how long you drink. this way you still gain and maintain some power without making the skill to powerful. Make it possible to cancel drinking by hitting W a second time as well.

instead of how it is currently worded.
Gragas guzzles down brew from his cask for up to 1 second. He becomes drunkenly empowered, dealing more damage on his next basic attack based on how long he drinks and reducing damage received.

Gragas guzzles down his brew and takes 10/12/14/16/18% reduced damage for 3 seconds. After finishing his drink, his next basic attack deals 20/50/80/110/140 (+30% Ability Power) plus up to 8/9/10/11/12% of the target's maximum Health as bonus magic damage
