Ideas for potential Zed Rework in the "Assassin Update"
With the QSS nerfs coming in soon and the Assassins Rework soon after, Zed is definitely going to be a 100% pick or ban rate and there doesn't seem to be a way to balance that by just tweaking some numbers. As a 
main since release, I'd like to hear some thoughts that could either
A.) Prevent a Rework B.) Design a Rework
I've come up with some idea's myself, no numbers involved but some concepts that could be tweaked into something viable.
New AD Item Idea
AD Zhonya's -esq : Vamp Scepter -> Creatively Named Armguard + Pickaxe = Creative Name
Armguard: basically the same concept as zhonyas, although instead of stacking armor per minion killed it's Life Steal
Now for the completed item, it could be a straight up Zhonyas. However i thought of a potential, more creative alternative, You gain stacks upon cs'ing regular minions 1 for minions 3 for Cannons 5 for Large Creep Each stack adds health to a Shield active to a cap of whatever. Basically a charging up barrier with a static but significantly smaller Cooldown. This seems to balance itself out. You can't just AFK farm between each fight so it's always up, you'll have to play a risk for reward finding decent times to farm without messing up your team, also trying to not get caught out while farming.
Zed Rework Idea
Living Shadow - W
Instead of scaling AD it would increase the damage of Shadow abilities by a percent amount per leveling of the ability, Still same CD and missle speed
Shadow Slash - E
Instead of instant cast it would be similar to a Darius Q, however, the longer you hold the E (up to 1 or 1.5 seconds) the more the damage and radius is. So technically you can instant cast but it would be way better for a charged hit especially with the reworked ultimate
The Power of the Shadows (dumb name) - Ultimate (R)
Zed marks an enemy for 3 seconds, for each ability landed over the span of 3 seconds(shadow abilities included) Zed spawns a shadow around his opponent for each ability landed. The space inbetween the shadow and the opponent on spawn would be slightly larger than the radius of a fully charged Shadow Slash
1 ability - Shadow directly in front 2 - Front and back 3 - Triangle with the point behind 4 - Square 5 - Pentagon etc
These shadows remain for 2 seconds and will cast the next ability(only 1) you use for significantly reduced base damage, however still receive the buff from W.
(optional addition) If Zed hovers his mouse over one of the shadows and presses W, he swaps with that shadow, sorta like an azir turret input
Zed Rework 2
Razor Shuriken - Q
Same thing as Live
Living Shadow - W
Similar to the other W I mentioned, This one does not have an AD buff upon scaling, this one offers a percent increase to shadow damage, however with the new Ult it has a different appeal to it.
Shadow Slash - E
Same as live
Death Mark - R
Zed marks his target, casting a shadow in front of his target and appearing behind them, after 3 seconds the mark explodes and deals (same as live) AD damage, also, for each time zed damaged his opponent during this mark, Zed strikes with a shadow for a flat AD amount each hit.
Basically for each ability you land Zed spawns a shadow and it strikes the opponent, think of the old Fiora ult, it would be a similar animation, probably just shadows dashing through her, and they deal a flat amount for each. The flat amount would be pretty low, but with the buff from W and the amount you can stack it.
This may seem disorganized and I apologize, but let me throw in a few more details.
To generate a stack you can do any form of damage as long as it's unique so.
E - Tiamat - Auto - Q x2 - Ignite (only 1 stack total for any tick) - auto - E = 8 Stacks.
Each stack is applied 0.4 seconds apart from each other, this gives opponents time to react but still makes it devastating if not prepared.
Stacks will do very little, but still reasonable damage, based soley on how well you can stack it, this will set apart good Zed's from bad.
You can still go back to your ult shadow like Live Zed.
Also, these are open to changes, it's not like this is the finalized idea, I'd like to hear your opinions on what could be better.
Thanks for reading. [slayer-pantheon-thumbs]
