Missing logic in the game

Since yall have destroyed the APCs yall (and/or the pro players) dislike, I would like to point out a logic flaw in an old-school character.

Kennen: his ball lightning effect (e) causes a mark of the storm to be added to anything he touches. However, if someone physically attacks him (punch, gragus charge, maokai's entangle, sword strike, fizz auto attack, gnar hop, etc etc) they do not have a mark applied to them. It's pretty obvious that lightning (electricity) follows a current, and will travel down every available arc to find a ground including going against gravity if it will eventually ground. So when anyone hits him, a mark should be applied, yet doesn't. I would appreciate it if this got looked into. If you're not sure about real life mechanics, ask any other physicist out there.
