Remove Zoe from the game until you can come up with a better kit for her.
There are plenty of Champions I've hated playing against in my years playing League (cough
cough) but it's almost always been either a numbers game that could be tweaked with buffs/nerfs, or a single problematic spell in an otherwise fine kit (
). Zoe, however, is the first time I've ever felt a Champion should've never been released at all. Her entire kit, every last part of it, is the epitome of 'bad design choices' and lack of fore-planning. Lane-length oneshots with a single spell, the most absolute hardcore RNG I've ever seen, rewarded for MISSING her abilities, the ability to cover all her own weaknesses with ease, and a complete lack of cooldowns or mana costs. A kit this inherently toxic and unbalanceable should have never been released into a competitive game environment, and it should be removed from that environment until properly addressed.
