Fizz Troll Pole
There is a significant amount of angry posts saying that Fizz shouldn't be invulnerable on his Playful / Trickster and many more posts stating that it should be removed from the game entirely. We all know that Fizz annoys us.
However, we are also fully aware that deleting the move or making him completely vulnerable during the Playful / Trickster would ruin him entirely. But what if, perhaps, Riot made it to where he was only Invulnerable whilst activating the ability, but was completely vulnerable while stalling out in the air. It would force him to use it more carefully and he would slightly more counter-play without completely ruining his kit.
