I would suggest your doing it wrong. If he uses W to trade, the you should get a very long Cd to farm safely and harass him back, if he holds on to it, then he really isn't that hard to deal with. Same thing with using his abilities to push wave, he uses Q to farm? you have a window where he can not trade very well. I by no means enjoy that matchup with most mages, but it is by no means the "hugging the tower for 10 mins" nightmare you make it out to be.
What? You've probably never played against a Diamond+ Zed main.
Zed puts his W on top of you and hits you with E + at least one Q. It's unavoidable.
That combo deals 473 damage at level 7 with only Serrated Dirk. Casters have about 44 armor and 960 health with Chapter. Lethality reduces the armor to 37. Total damage taken after armor is around 347. That's 36% of your max health.
If he lands two shurikens, it does about 443 damage, or about 46% of your max health. This is low enough for him to just ult and kill you once his cooldowns are back up.
You now also have to play around his shadow, because it effectively zones you from the wave, and you're creating distance from your turret by side stepping around it to continue CSing. Zed can use this for cover while he picks up some CS before the shadow drops, then get the rest from a safe range with Q, only missing maybe one or two.
Absolute worst case scenario, he does this twice and always misses the second Q, and the third time he can kill you with his ult. It's unavoidable damage, and most mid laners have no way to reliably trade with him when he does this, either because the minions are blocking your skill shots or because he's too far away to guarantee a skill shot lands.
If you try to rush Armguard, you just delay the time he needs to kill you to three W + E + Q combos, instead of four, with the added bonus that you quickly run OOM and have to leave lane, giving him plating gold, priority over objectives, and also free roams, which is potentially even worse than if he had just killed you.
