Kennen rework

So, I love playing Kennen. He's a very fun champion. He really can go any lane, and I recently started to try him as an adc. At first, I thought "Aw crap, this is doing to fail really bad" cuz I had previously seen and fought against Kennen adcs who failed miserably. Once I got into late game though I realized it really does work well, it just takes a little change from the usual AP build ability dependability. I also realized after a few games that my opponent does end up with a huge ability advantage due to the fact that Kennen's abilities can only be enhanced by ability power, not attack damage. While there is a big difference in q, w, and e, the biggest difference is the ultimate. In my opinion, Kennen's ultimate is already insanely powerful because of the fact that at max it does (Not 100% sure, don't quote me on damage) 110 damage every half a second to all nearby enemies while applying a mark of the storm for each hit, and the ultimate lasts 6 seconds. With an adc build that damage is stuck at 110, while other champions, such as Jinx, already have much more range with their ultimate, can increase that damage to go for long range kills. Sorry for all the people who just read that cuz it probably didn't make much sense, but I would like to see it so that 1 or 2 of Kennen's abilities if not all can be enhanced by ability power and attack damage. I do understand that this probably will never happen, but I figured it definitely will never happen if nobody suggests it, and it can't hurt to do so.

Also a little random thing for all the other Kennen mains in general, not just the adcs, Do any of you others seem to find it hard to get S's on Kennen? I'm mastery 5 with him and only have 1 shard. 22/4 isn't an S-, so I don't really know what is.

"Balance in all things" - Kennen Hopefully a little more balance in the Kennen adc.
