I'm just gonna throw in my vote for Kennen Visual and Gameplay Update

No legendary skins (but the flash cosplay is hella fine), no animation on taunt, no special crit or W passive attack animations, no sprint animation, 1 attack animation (including abilities), and he's never had any significant work done on him. Just tweaks to his ult and passive. I mean I enjoy playing kennen, but his kit is really stale. I would at least give him a visual update after nunu. He really absolutely needs it.....

but don't touch his laugh animation, that shit is hilarious. I killed a darius and was side by side to his corpse spamming the laugh animation. It felt like that deadpool trailer where he lays down on the dead guy after taking forever to get ready in the phone booth.
