Suggestion to improve the quality and fun of rotational game modes

Here's an example of something that happens to a lot of us. *Me game one: Oh boy, the new game mode is out. I cant wait to try all Caitlyns or Fiddlesticks. I see we are going against all Malzahar.. let's hope he's not too rough...

*Me 10 games later: Okay I'm sick and tired of seeing Malzahar, Brand, Zed, and Ekko every fucking game.

My idea is to disable the top 10 MOST PLAYED champs during the game modes period in the last 8 hours of it's existence. Don't say "that's what bans are for" when there is too many champs to ban. Your first pick might not ban Zed Ekko Malzahar. You might get hit with a premade that wants to do all Bard and as soon as you are matched vs Zed you instantly want to end it. This is not fun.

Also make a game mode where the top 10 most played champs are banned period. I would play the shit out of that.
