5 Premade vs 5 Random

We should get a rasonably fair opponent in league when queueing up. i got matched with 4 other randomly selected players to play against 5 premades.

I dont know how this is even possible. I think it is totally unacceptable and ruins a lot of fun. i have noticed this in other matches too that the premades are unevenly distributed but this is just not ok. How do you expect to be reawarding to play against such teams
