These bandaids are doing nothing for Kennen

I've mained him since S1, at Diamond/Platinum before Diamond existed. He's currently unplayable.

I just tried his new ult buff. Do you know what happened? The same thing that happens every time you pick Kennen at Diamond. When I tried to get into range of a carry after our front lines engaged, the enemy Karthus dropped his wall on me and completely negated my mobility. Resulting in me somewhere near their front lines, but not in range of their carries. Which is a great position for the enemy's carries to kill me and/or force my Zhonya, rendering me useless.

But he can't drop his wall on me every time, right? He missed it once. I went around it and almost got to the carries, and then their Blitzcrank knocked me up and pulled me out of the knock up, while their carries killed me. Once again forcing Zhonya and rendering me useless, unless you want to consider ulting on Blitzcrank useful.

But Flash helps, right? I once flashed into the enemy Caitlyn. She netted out of it, crit me a few times, and that was that.

Kennen can't be fixed with tweaks like this. His kit just doesn't work in the current state of the game. He was a good pick in season 2, but there's too much mobility, CC, disengage, and burst in the game right now.
