So, a lot of uproar over Zed, I know how to fix him...
a while ago, back the last time
was rearing his ugly mask, I proposed a single change that would instantly balance him...
you see, the problem with
is not the mobility, not the burst, its the poke and wave-clear. He is manaless, which means if he can shove lane, he will, and force mages to go back because they ran out of mana. So he needs to lose his wave clear. Well, what do you know, he has two high damage AOE abilities, one of which is the ability he maxes first. That is stupid in a role designed to be single target and melee-ish range.
So, how do we fix him? Have his Q be a single target skill shot. Maybe buff the damage or the energy cost or something is needed.
What does this do: well, he keeps his wave clear from his E, but you don't max that early on. Looking at his poke, he still has some, his Q is still poke and a W+Q combo can increase the chances of landing one or both, at the cost of his mobility. his W+E combo can alos poke, agian at the cost of his mobility.
You see, it is my belief that any burst champion, be it mage or assassin, needs strong and weak points durring the laning pahse where they can be punished. Like Blitzcrank if he misses a hook, his pimary engage tool is down, harass him for it! But Zed does not have these weak points at this moment, he only needs his Q to poke and clear waves, keeping all of his other abilities ready for an all in or escape. His Q also has a short-ish cooldown, meaning his harass is constant (energy, not mana), and his Q can be back up for an all-in quickly. So forcing him to expend his mobility for easier harass seems like a fair trade off.
TL;DR I just don't want his poke and his waveclear on the same ability, especially when that ability also has a decently low cooldown and non-existent cost
Edit: Let me try to be clear, Zed has seen little talk over the Tank meta, due to their being beefy champions constantly protecting the carries, but when that goes away, I assure you people will start complaining about assassins again, and a manaless assassin with wave clear will be sure to draw attention.
There will always be QQ threads about these champions.

in a fraction of a second; furthermore,

to take down towers just as quickly. Zed's wave clear pales in comparison of other assassin's such as
's or
's.
and
for example can easily win lane against Zed.
