A few QoL buffs for Zed

I've mained Zed since s1 so I'd like to give a few suggestions to make Zed a little smoother in terms of gameplay.

First off, his current passive is almost unnoticeable. As I'm sure all of you know, 10% max health in magic damage is absolutely nothing, and doesn't synergize well with the armourpen Zed buys. My proposed change is that we turn this magic damage into true damage to compensate. The damage should also not scale, and start off as 20% rather than 6%. The cooldown of this on targets should also be lowered to 1.5 seconds to compensate for Zed's complete lack of DPS on his autos.

Next, his Q is a very awkward and hard to hit skillshot. It's hitbox is tiny and is one of the slowest in the game. Also, after the first target, subsequent targets take less damage. As I'm sure all of you know, Zed has 0 waveclear, so it would help to make it so that the Q only does reduced damage after the first enemy champion. This would also be helpful when minions are in the way and you want to get a full-damage Q on your laning opponent. The range should also be buffed and the projectile speed and hitbox doubled.

His W is probably one of the worst skills in the game. The cast time is horrendous, and 25% bonus AD makes no substantial difference. I suggest that the animation of the skill be made 2x faster, and shadows automatically autoattack enemy champions in their range, dealing magic damage that scales off of AD. This fits thematically because it is assumed Zed is using some sort of forbidden magic to use his shadows. Also, the cooldown should be lowered, as Zed is extremely easy to gank when he uses his combo, and this would help him achieve a safer lane phase.

His E is just terrible. It has no damage at all, and the meager slow is barely enough to stick on to your target. I was contemplating requesting this to be a 5 minute knockup for synergy with my other favourite champion, Yasuo, but I found a better idea. Every time an enemy is hit with an E, its armour is reduced by a flat amount. This effect can stack up to 5 times. In addition, the cooldown of this should be reduced by 1 second every time Zed attacks a champion he hit with his E so he can stack it up faster.

Lastly, his ult is probably the clunkiest part of his kit, especially after the gigantic nerf. To compensate, Zed's target should blow up the moment he does enough damage for his ult to kill the target. This is to prevent his target from buying those 0 counterplay items like Zhonya's and QSS. Also, he should be untargetable for the entire duration of the ultimate until his target dies. This solves the problem of Zed being instantly blown up the moment he goes in.

I think these changes would be beneficial for Zed to return to viability as the healthy midlane assassin he used to be.
