"Zed is broken"
Alright this is a reality check.
It is so boring to see all this hate on Zed. Why? Does he make lane hard? Does he one-shot you all the time?
Listen to me, there is counterplay to him.
Low Elo, where most of the complaining comes from, has a lot of Zed players in there. What low-elo Zed players do normally to harass is shadow, and Q-E or E-Q. This is pre-6. If you are playing an immobile mage, yes you won't dodge that well, since he is a lot more mobile than you. However, if you play someone like Fizz, Yasuo, LeBlanc, or some mobile mage or assassin, you can dodge that as soon as you see the shadow. Yes, he deserves to be nerfed a bit, since his damage is a bit too high, but he is not flat out broken.
In high elo, Zed players are much higher skilled, and know the ins and outs of him. However, his lane opponent should still know how to anticipate his movements and poke pattern.
And yes, items do count as counterplay. Zhonya's is a must on most burst mages, because if they fuck up they will die unless they can save themselves with a few seconds of invincibility.
All in all, his power is extremely overrated, and he does not deserve to be dumpstered. His nerfs, and compensation buffs, are totally in line. If you still have a problem with it, learn to play against him, stop whining.
This was not in line with my usual demeanor, I'm just sick and tired of all this blind hate on Zed. Sorry about that.
