zed was nerfed in S6 because he was too lane bully for an assassin.

then his damage. in which was never a big deal. look zed's damage is not as impressive as a mage. or other ad assassins. zed's always been low damage champion. he always pokes someone down in lane. before he ults and kills them. mid game if he snowballs he might R and land acombo for a kill. but late game comes around and he has to do the same thing he does early. in which secure kills and not 100-0 people because thats unreliable.

currently sitting at the 3rd worst winrate mid platinum +. zed is not a champion that was broken in high elo. or low elo. or even pro play. he was nerfed because of a vendetta against him. I like to play zed because hes a fun champion. I know he isn't the most reliable to win. hes hard to pull off but even when you pull off the best combo possible. right now he just does no damage. compared to anyone else that plays his role.

you can't really freely use W in lane anymore because of extra 4s of cd. and you can't 100-0 someone in lane. you don't get free ad in lane before you kill someone with good ad with your ult. his lane is worse. his late game is worse unless there is a jhin with 600 ad on the enemy team. with shields and what not he can't kill anyone. hes just weak. too much delayed damage on the ult. and there is just too much defense against him. hell I'd argue that hes no problem in a 1v1 anymore. lucian can 1v1 you. I've had it happen many times. and am not the only one saying that scarra too.

"how dare those peasent assassins farm in my lane. am a mage. thats blasphemy!" yall remember that. people saying you don't deserve a decent laning phase for being an asssasin. as if late game assassins are not the hardest thing in league of legends to pull off. because they are

tldr: zed is weak. if you wanted to nerf his lane fine but u shouldn't have nerfed his already unreliable assassination potential.
