Twitch Q visual suggestion

Once Twitch activates his Q, it's several seconds before he becomes invisible, but he turns transparent right away.

I was in a battle with Renekton, activated my q, and tried to run away. I was out of his autoattack attack range, and realized that, since I'm not taking damage, my q must have already fully activated because I look invisible.

It turns out the Renekton had flame cloak--which you can't bloody see on Renekton easily because his character model is so large.

I looked at Renekton: he didn't look able to hit me. I looked at me: I was transparent. In every single video game, being transparent means you are invisible. That's how every game operates.

Why not give Twitch a swirling aura around his feet to signify he's trying to turn invisible, instead of making him look invisible before he actually is?!!
