Whats the counter play to zed?
Okay just going to throw this out there
is a decent counter to zed but his ult cooldown at level 6 is 120 seconds. ( Dont know if its been changed just looking at lol wiki)
Zhonyas has a cooldown of 120. But zed can build cooldown for his ult you cant for zhonyas meaning that atleast zed has 25 seconds to go in on you.
Okay lets for say zed is bad at skillshots? It doesnt fucking matter because with energy he gets to throw out as many as he likes and god forbid you get by his shuriken or slow your dead.
And you cant ward against him if your botlane either because of this cancerous item that needs to be removed 
And you cant just all him or else he will just one shot you.
You cant gank him Cuz of w
Whats the counterplay
At least give zed fucking mana so I can punish someone that misses 5 q's
(yes chogath mid) I'm not going to say zed is balanced and you need practice BUT you can pick these champions up and use your minions to lower his q damage if it hits you etc..
