Zed has had a 50%+ ban rate basically since release and nothing is wrong with him?
Zed is stupidly annoying to lane against. If he q+w+e you with electrocute will put you at <30% hp and your lane is basically over. He doesn't even need to kill you with his ult if he has ignite and can right click. Additionally, he has more poke, more wave clear, and access to better itemization than mages. What can a standard immobile mage do against his toxic kit, hexdrinker first back, duskblade, and nullifying orb? He doesn't need a nerf; he needs a rework.
