New champion released should not be played on Ranked games for a set of times

When a new champion is played on a ranked its either they do ultra godlike good or just complete garbage.

They either becomes freelo or elohell. Not only that they becomes a Must Ban champion which leaves other must ban champion free. Anyone in ranked game has alot of experience in the game already. They only need like 2 match to get a hang of that champion. Trust me All chat you dont need 100 games with them to get good this isnt fighting games like Street fighter, mortal kombat or other games like Starcraft. You can`t get a hang on 100 games no you need more.

League of legends start getting less and less champion mechanics with those incoming nerf aswell as Meta shifting items such as Luden echo, Cinderhulk, Black cleaver and upcoming godlike item abyssal scepter.

But this brings my points. What if a champion is already strong and are given even strong items?

Would that makes them unstoppable?

Here are the strengh of ekko that needs to be turn down.

Passive: 231 + 70% ratio + 80% slow for 3 second + spell effect applied. I don`t know what you guys were thinking.

Q: Increase its mana cost early and max rank unchanged. Because this is his spamming abilities.

W: another inbuilt ability + passive clap clap clap how many passive you want to give to new champion? 3 or 4 or6? That Shield Doe Riven must be jealous now.

E: Seems fine to me I see no problem with that.

R: doesn`t need any change.

What is Ekko? A fighter or an Assassins? Because he is utterly tanky with that shield and base hp. That health regen that mana regen that base attack damage.
