I want to ask WHY ?

I want to ask why did Riot changed league of legends ranked games to enable every kind of premade ? There is al ot a of ppl like me who trying to play ranked have not so many friends who willing to play with me....clubs didn't works too. It's actually ruins the gameplay for me because if 33 ppl palys together in one of the teams , and has a great communications with each other they will win the match anyway, and it's create an unfair advantage against the enemy team since if tehy are not premade they they can't talk as much as the enemy team can. It's different from 5v5 version of premade since they prepared for this, but not 5 random guy who get selected randomly , against a premade enemy team.

Of course you can say that we have the chances to create teams but this is not the case....the case is this is actually decides the match before it starts. I've met a lot of premade teams in ranked as enemies while we had zero premade....
