turrets still dont take percentual damage - that means they are useless and players dont take them seriously after few minutes
I agree.
Zed is still impossible to fight againist, teleport in and out, dealing massive damage, all this while invulnerable and under tower at lvl 6
"Teleport in and out" like he's supposed to
"dealing massive damage" like he's supposed to
"all this while invulnerable and under tower at lvl 6"
Bullshit. Zed doesn't have invulnerability. Furthermore, if you're 60% health and below and Zed has more health, then he can easily all-in you. It's your job to outplay him.
Blitzkrang most banned champion ever, his Q which basically wins matches still hasnt been nerfed (range)
Not even. I've seen Darius banned more.
FIzz - overpowered invulnerability from E
Jayce - ridiculous damage + range from Q
I agree about Jayce, but Fizz also does not have invulnerability. It's also fairly easy to punish early game if they misuse it.
Katarina - teleport and kill all, still same after 2 years
Teemo still OP
Katarina at least takes skill, unlike her kit two years ago. A good Kat will shred entire teams of squishies, and it's up to your support or tank or jungler to stop them from moving so that the rest of your team can shred her. She's not unkillable. Neither are Jayce, Zed, Teemo, and Fizz.
Velkoz E still underpowered
Concerning the new champs, Kayn - ridiculously OP and Aurelion is weakest champion ever
I agree about Vel's E.
Kayn is not even OP lmao. You're delusional if you think otherwise. He has the WORST early game, both in lane and in Jungle. As Shadow Assassin, he's SUPPOSED to burst you. As Rhaast, he's SUPPOSED to survive a 1v3. Not to mention that ASol isn't the weakest champion ever. That title goes to Nunu or Ivern.
High amount of invisible champs which gives you IK after invisibility fades out
It's not that many. Most of them are assassins. You know, champs who are supposed to hide and get you off guard??
an argument COULD be made for 
and then you have
