A Possible Kennen Buff

Playing a game the other day I realized something strange. His E.

It states "Kennen morphs into lightning form, enabling him to pass through units. Each enemy unit he touches takes damage and receives a Mark of the Storm." Enabling him to pass through units - ignore unit collision (Unit meaning minion and champion.) he can do this, he can't do this its own specifics. My example. E winds up and charges forward at who also used his e. Kennen still gets hit and knocked up. That doesn't add up. Yes you can argue Galio E is a spell and not a unit but regardless, it's still Galio. And don't you give me any of that anti-magic lore neither. This was an example. Same thing applies to Sion R and Rammus Q. He should be able to ignore these things. I don't really mind if still takes damage but at least take away the CC. Yes he can still be hit by every auto known to man...

Tl:DR Champions using their unit collisions as a means to stop Kennen when he's in his E should not be thing. This would give Kennen a much needed buff. If you think that's absurd, look at FIZZ. PS: I hardly ever play Kennen. I just think it would make things more fun.
