Our two little yordle friends here have been utterly forgotten in the Fields of Justice. I want us supporters to band together to plead for the model overhalls of these two strong yordles. As everyone is getting some love, these two are cast aside and I will not stand for it any longer! Please help these two and give them the support and update that they deserve! 
Poopy rework is Soon(TM).
No word on Kennen, though.
I thought Kennen was doing great earlier in the year during the assassin meta. Most champs get their time to shine. I really think Ziggs will be making a comeback soon because this tank meta will facilitate the need for siege comps once again.
Kennen is mostly fine..?
I do wish he'd get some more AD scaling, but what does he need?
I just don't think he needs anything at all.
Model wise, Kennen could definitely use an update in the model and animations. I definitely wouldn't want him to get a Tristana level design change though. I think his design looks fine as it is.
poppy is already getting a rework, riot says its sion level so its basically a full relaunch
