How to prevent future Smurf or Smurf making more Smurf

So I got this idea from a game called "Paladin" something, its kinda like OverWatch and HoTS combine and shitty shit shit

The idea is for every new players to have at least 5-10 Champion with mastery level 3 or 4 or maybe even 5, but with the amount each new players will spend playing and leveling up their account they should have enough experience with at least 5-10 Champion getting them to at least level 3-5 mastery

Once they get this certain amount of Champion to this mastery level, then they can Rank with level 30 account.

Smurf players, only like spamming 1 or 3 Champion at the most, so doing this will maybe prevent players from smurfing or making alot more account to Rank up on.

Now the other story is Smurf isn't even the problem anymore but I'm just adding ^^^^ that idea for some shit reason for lower tier players Smurfing is prolly an issue in the past but now? The issue is the players themselves and the stupid Rank, Match Making system of not balancing the Team well with each other

Because of Que Time Riot decided to just fucking put all elo together into a fucking match to help shorter que time, this happen in all elo even Challenger elo

Riot never keep their words

Also because Riot focus alot more on their Esport, they don't really give a shit about the gameplay for the Community

The only thing Riot is doing for the Community is

More Skins More limited LOOTs, such as Those stupid Hextech Annie skin More worthless Icon that doesn't benefit the game More Skins More Skins More Champion More Champion More Skins More Champion .................

The only thing they do for the Community is how to get your MONEY
