Zed is way too strong is lane
I wanted to examine, how favorable are zed's match up V. various mids and who can do well against him at Diamond ranked where I assume both players can play their selected champion to nearly its highest potential.
Zed wins 51.95%, although Azir poses an escape in the form of his E and strong early game poke, Azir has quite low starting armor leading zed to have an advantage over him
55.05% Zed's resourceless poke and gap closers allow him to easily beat long range mages
59.75% Zed can easily push Fizz under tower, is manaless, has better poke and damage
50.81% Despite being one of the strongest bullies at mid Syndra losses to Zed
59.05% Simply dodge the tornado with either your ult or shadow and bait windwall
42.71% Another midlane god who easily beats Zed since he lacks a way to stop Death Lotus
51.18% Despite her massive skill celling and potential for plays Zed still wins
50.45 Despite being cited as someone who does well agaisnt Zed, Zed still wins
50.00% Another sometimes cited Zed counter only goes fifty-fifty with Zed
56.19% Zed beats one of the other oppresive midlaners easily
TL.DR Very few mids can actually beat Zed. Long range casters get outsustained and jumped. Lane bullies such as Syndra come the closests to beating Zed but still lose more than they win. Zeds "counters" mostly Lissandra and sometimes Ahri dont win more than Zed. Zed destroys most other assassins such as Fizz. The only mid that can consistently win is also questionably way too good. Is Zed too strong, you can't wholly base it on win rates but I do know playing mid against Zed is nightmarish lack of fun. His laning is his biggest problem I think perhaps fixing it can allow him to balanced?
