Could we have a bettter blind pick matchmaking?

I usualy just read on the board, but i come across a huge problem in the last couple of weeks.

Blind pick games can feel horrible, and no i am not speaking about the clown fiesta. I just went against a 4 man premade made of gold plat and diamond, when my team were my duo and random's.

it was an absolute stomp. the game was over at 6 min.

Tell me how i am suppose to have a fun game when i go against an organised team with a diamond, or how i am supposed to win.

And its not the first time, earlier this month i got stomped by a 5 mans premade. Why those 4-5 premades team cant go against each other?

I dont mind losing when its a fair game, but goin against premade team with people way above my skills rating just feel like absolute trash
