Playing mana intensive AP mids VS Zed is beyond annoying.
With the not so recent mana regen nerfs, laning vs someone like Zed just became harder that it already was.
Before the mana regen changes, rushing an Armguard already affected your laning, you'll go oom so fast and can't keep up with Zed's manaless farming, now it's even worse.
I don't understand how I'm supposed to keep up with Zed as Lux (for example). I stay far away for max range spells, he has ways to bridge the gap. I tower hug and farm under turret, he can dive easily without even getting a single tower hit. I might finish the Zonya and be able to dodge his ult, but his QWE alone + ignite is enough to kill me again.
I think it's a big issue when your only option is to play a certain champion just to counter him.
Edit: I know Fizz is also a big issue right now, but he also uses mana, so he can also go oom, unlike Zed.
Try this, except - wait for your jungler to initiate before going all-in.
Despite popular belief of where people think Xin Zhao should be laning, I honestly believe he should destroy Zed middle.
