I'm kinda confused with match making these days. Is it possible to get an explanation from a riot member about the case mention in the link I added to this post.
How is it possible to get a 5 man pre-made game in ranked flex with an average tier of diamond 4 is queued against a 3 man premade team with an average tier of plat 2/3 ?
I can accept that it is possible to have higher tier members against each other, but 5 man pre-made full tier up above the enemy without a 5 man pre-made? That is just a wrong algorithm / poor matchmaking.
Thanks for reading and I hope to get an answer from riot games developers themselves!
