Just an idea for Fizz
We all know how much of a controversy fizz is, But what if you could hit his troll pole? Like abilities, auto attacks ,ect would be able to hit it. Just 1 hit would be enough. Essentially what this would do is it would prevent the 2nd half of fizz's E. If you were fast enough or madlife enough you could knock the troll pole out from under him, removing both the damage portion and his second hop. No need to stun him for it since I think that would be too much of a nerf, but I believe its a good start for counter play on fizz.
For example: blue team is at baron, they have a ward over on red sides jungle. Caitlyn sees fizz is near the wall, she readies up her Q, Fizz tries to hop over the wall and caits Q, however the Q destroys the pole trapping fizz in baron pit with blue team, he might score the baron buff, but hes not getting out alive without a flash.
It forces him to be more cautious with his troll pole, trading damage immunity for the risk of losing distance on his W or even damage upon an engage.
Obviously for people who quickly hop on and off timing the hit on the pole is much harder, but still possible.
TL:DR Allow the pole to be hit. fizz can negate your damage, now you can negate some of his damage and mobility
