How to Fix Zed (Zed player here)
Before you downvote me to oblivion because I like to play Zed, this is purely a thread I'm creating to try and fix him being OP while still being very satisfying to play.
I think people are overestimating Zed's power at the moment, sure, he's strong, but he isn't broken. I just wanted to get that out of the way before we begin.
Increase the energy cost on his Shuriken, but make it refund a lot more if he hits both. This makes it so that it's harder to farm with it, and it rewards the Zed player for going in and hitting his skillshots.
His W is fine the way he is, perhaps even lowering the early CD would be a nice counterbuff.
Increase his E cooldown by 1 second early on, so he can't use it twice in one length of a shadow duration. THIS IS THE BIGGEST NERF! From what I know from playing Zed, hitting two E's is pretty valuable to his laning, and this will ruin his poke. He is forced to go in for damage with this.
I like the way his ult is now, but if you guys don't like any of the changes I suggested above, then I think I have a big fix for his ult.
When he ults, instead of putting Zed behind the enemy, put a shadow there. This makes it so that instead of using his ult as an escape, he has to use it to get in range of auto attacks and his BORK. It will be much harder to use the shadow to escape, he must either use his W offensively to get more damage or use it to get out, forcing a decision on the Zed. If any change had to be made, I think it would be this one, because it nerfs everything about his all-in that nobody likes to play against.
