I have recently picked back Kennen and i absolutely loved him.. his team-fight works amazingly well and he literally melts both apc and adc. His CC is just so strong.. why is he underplayed? Why doesn't he fit the meta? I rarely see him in games.
Two skins I would liek to see on him is South Park Kenny and Pikachu.
he's also a pretty strong adc... xD
Spam everything stun them..
Well I beat a draven.. lol
PIKACHU IS NOT A RAT YOU %@=% !!1!11!!!
He isn't played much because he requires really good positioning. If you don't position well, you get blown up. However, he is a really strong champion who can probably play every position in the game.
He has a strong laning phase and mid game, but falls off later in the game. He is also a very simple champion, so outside of flashing in, his initiation is very telegraphed, making it easy to stop it. Also, just to name a few things that kind of dump on him are 
. If these are used at the right team, his team fighting ability is completely shut down. Also another problem with him is he is ultimate reliant, not being able to fare well in teamfights without it.
I'd rather not see more ranged manaless toplane cancer.
Because he's incredibly annoying to lane against. Bullies out most melee's from farm and spams stuns nonstop with no resource. Riot themselves admitted he was poorly designed.
Also I have a personal hatred of mages who abuse 
to remove any semblance of counterplay from their ults, it's a terrible interaction that shouldn't exist.
