Can't play Blind/Draft normal games

Because everytime I do I get put in in plat+ all the way to diamond 1 games.

Why is this even a thing? I am a silver player, if I get matched against a plat/diamond there's a 80% chance I will lose lane and make the enemy laner snowball out of control.

I am AWARE that what causes this are premades, and that on the enemy team there's a player just like me, of lower rank, at this point the game becomes a "who can snowball better off the lower elo players", that, assuming that both the lower rank players are indeed low rank players (I'm looking at you smurfies).

Does all that make it any more fair? Of course it does not, I am still playing versus people that are more experienced than I am, I am bound to fall behind.

I can already hear people typing "Git gud" in the chat or stuff like that, well I can't git gud if I can't practice, normal games are for that but is just impossible to learn anything when you constantly go against people that are way better than you, is like having a box match against a top tier boxer and you only barely got the basic training, you're his punching bag and the only thing you can learn is how to get hit.

This makes the game awfully frustrating to play, no one want to be be the punching bag.

What I would suggest it making so that if someone plays with a higher rank friend they get marked as the same rank.

For example: is premade with is silver 4 is diamond 3 gets marked as being diamond 3

This way on the enemy team there will not be a player near the division of Janna.
