How the hell is Zed anywhere near balanced? Does the balance team even play the game?

I dont understand, you say Rengar isnt a healthy assassin and then gut him, but you let be like he is? Zed paired up with a Duskblade is horror. You can literally R on ADC > E > Q and R back to your shadow to safety. Rengar at least will die in the process..

In general I dont know if the balance team even plays the game, why the heck would you buff to oblivion? Why does exist in her current state? Being a "manaless" lane bully that has true damage and is tanky with an AoE heal. Btw, why can Fiora parry Exhaust and Ignite? I am pretty sure if someone puts you into a burning house or gas chamber you cant parry that..

There are many more problematic champs at the moment such as

My request for the balance team and Riot would be that you should fix the champions already existing in the game before implementing new one's, or is that too much to ask for as well?
