Concept to make Fizz and Zed strong, but not oppressive
The problem with Fizz and Zed is that they are very safe assassins. This makes them quite frustrating to lane against, even if you're ranged, since they can harass you with abilities and not have to worry about any kind of threat that you pose, since Zed can outrange you, and Fizz and jump away before you retaliate.
This change is so that Fizz and Zed can still poke you, but they will have actual counterplayer now.
Fizz: Playful / Trickster: No longer makes Fizz untargetable. Instead, Fizz dodges all incoming auto attacks and crowd control effects, but he can still be damaged by AoE abilities and the turret. If Fizz takes a certain amount of damage while on his pole, he will be forced to crash down at his current location after 0.25 seconds. As compensation, damage on his E is increased, as well as it's slow amount.
Zed: Death Mark: Shadow is now placed BEHIND the target rather than at your original position. There is now also a 1.75 second delay before you can swap with any of your shadows. Also, if you get further than 1000 units away from your shadow, you cannot swap with it. Zed's shadows can now be killed by champions as well, with 2 auto attacks, or 1 spell cast on it. Killing a shadow will net you 10 gold. If a shadow is killed, Zed will lose some energy. Damage on Zed's Q, auto attacks, and death mark are all increased as compensation.
The thing to remember is: Fizz and Zed are ASSASSINS. They are meant to be able to kill you quickly. The thing that needs to be balanced is the counterplay options that are given to you so that you can avoid getting killed. At their current state, Fizz and Zed are able to easily bully a RANGED burst mage out of lane, and if they try to counter them, they can easily just jump on you, tower dive, and kill you, and there is nothing you can do about it. The only way to stop their aggressive onslaught is to either: Buy Zhonyas, (which is good against Zed, but he can counter with armor pen) or just sit away from your minions and lose a lot of experience and gold. Unlike literally, EVERY. OTHER. MIDLANE. ASSASSIN. Fizz and Zed are the only ones who have limited counterplay. Talon is difficult to outplay, but he is quite predictable, as well as if he goes in, he cannot escape.. Katarina just needs to be cc'd and she can't all in you. Yasuo could use some balance as that dash of his is really frustrating, but he isn't as frustrating as Fizz or Zed, because he can't tower dive as effectively and his attacks can more or less be dodged.
Turret shots: Now deal 5% of target enemy champions health as additional true damage. Each shot will double the amount inflicted. (5% on first shot, 10% on second shot, 20% on third, etc) This damage is applied only to champions. Inhibitor and Nexus turrets now deal 9% of enemy champions health as true damage per second. This damage increased by 1.5% for each tick of damage inflicted. All turrets now slow enemy champions attacks speed and movement sped by 15% if they are being focused by it.
"Wow turrets are so overpowered. They deal so much damage." -said no one ever. Turrets are so weak right now that turret diving now isn't as risky as it was a while back. Turrets are meant to be beacons of hope, a place where you are safe-ish. In their current state, they are not doing their job.
