Please for the love of god , Take the teams of 3 and 4 out of ranked

My most recent game was myself playing top (solo q) and then a premade of 4 (mid,jg,adc,sup). I finish the game 10/7/3 with a 6/1 start. (note i had to do this with zero ganks because the rest of my team was grouped up and the jgler refused to come topside because he was stuck up his buddies butts all game.) The other 4 go 12 kills and 35 deaths. I ask them why they are playing ranked like this and they said they just like playing together. And that is perfectly fine but please get that shit out of ranked. Most of my games with more than a duo in the game are so lopsided because one of the groups of four actually play together and the other group of four does not ever play together and the result is me most likely being with the premade 3's and 4's that do not play together and are just throwing ranked games in the favor of the other team who actually has a group of 3 or 4 that play together often. Please take this out of ranked and let that shit stay in normals. If you want to play a ranked game with more then a duo then make a team of 5 like it used to be.

It just seems to hard to accurately balance the game when you let groups of more than two in ranked. Please change this back
