Kennen- Quality of life changes and possible W (active) bug

I am a self proclaimed Kennen main. I have close to 200 games with this guy, which to many may or may not be impressive. For myself, my pick rate for him far, and I do mean far, outweighs any other champion. Using him, top lane, every chance I get, this little bro took me from Bronze 5 to my current seat of Silver 3. I would like to think I know more or less how to use this little bugger.

My suggestion/discussion would be this: Once you have a stack on an enemy, be it minion or champion, you can cast your W which deals damage and adds another stack of Storm to targets hit. Currently, activating W causes Kennen to awkwardly pause. Maybe my timing is still off, but sometimes when I have my auto-attack ready to proc a stack of Storm, I can hear the "swoosh" of him doing his auto and then I immediately follow through with hitting W to either ignite his proc or go for the stun. The problem is, activating W after hearing the "swoosh" causes Kennen to freeze and his auto doesn't go through. (This is assuming enemies already have a stack of Storm from either Lightning ball (E) or his shuriken (Q).) Doing the above you can easily miss a stun opportunity by trying to listen for the auto going off, making you feel like your passive W auto should have left Kennen's hand, but really hasn't.

The same goes for his Ultimate. You get an awkward pause after/during it's cast. The enemy could be in the AOE of your ult, but the little pause can easily give them enough time to move out of it's rang, making for a silly looking wasted Ultimate. While in a fast-paced team fight this little pause can come with some other negative side-effects. Not bugs, but assume this scenario:

• You rush into a fight using E and apply stacks.
• You activate Ultimate while still in ball. You pause.
• You cast W to stun/add marks. You pause.
• While in your E lightning ball form, you expect to have mobility. These pauses create a very short but very vulnerable period of being mass focused and easily killed.

The possible bug: Darius, no matter if you Flash or seem to be outside of his grab range, he will grab you under visually impossible scenarios. As Kennen, I have had issues with casting W while an enemy Champion was the only one in range with a Mark but quickly moves out of range during my cast. Kennen give's his little shout, the spell goes on cooldown, but no effect from his W. If Darius can have impossible ranges to grab people, why can't Kennen get his casts off when the ability indicates someone is in range to do so? In a fight scenario, say you get an enemy's health into easy kill range. You Have a Mark on him, but he is far away. You use E (ball form) or Flash to be in range, but because of the slight pause, the enemy can invoke the "the possible bug" and your spell goes on CD without actually doing anything.

The quality of life/quality of feel: I want to know how groundbreaking it would be if_ these pauses could be removed. If not 100% removed, could a small buff be in store by removing these pauses when he is in ball-form_ only? This wouldn't be a very significant change but when it comes to spell-chaining and playing a very physically weak champion who has one of the best engages in the game, these pauses are little, but can be a big headache to dedicated Kennen players and can result in awkward movement/sub-par expectation and deliverance to your team.

Again I note, maybe these pauses are very intentional and maybe I just need to adjust a little better, but I feel a quality of life/quality of feel improvement is justified here.
