You can mess around with her numbers all you want Riot but her kit is just frustrating to play against on another lvl. Far more then the likes of Zed/Yasuo/Illaoi, etc.
Zoe is basically pre-rework Nidalee with far more versatility. She has incredible pick potential even if she doesnt' do damage with her absurdly long range bubble if it goes through a wall. Its just so insanely frustrating to play against her, having to have to back every time she hits you with any Q as it does 80% of your health if you aren't incredibly tanky with MR. Added to the fact that she does an absurd amount of damage for someone who isn't even very fed. A 1/3 Zoe in lane with little farm and half an item will chunk any squishes health with any Q, even almost kill them if she hit a bubble.
She can be balanced and have a fair win rate but thats not going to fix her kit from being so frustrating to play against. At least Old Nidalee was single target, Zoe's is aoe.
