I don't understand why this matters?
If you are serious about the game then why aren't you finding people to play with in a pre-made team? I mean it is a team game and playing with random people you will never be able to reach your full potential so if you have ambitions to rank up and play in championships someday look at the column to the left and you will find a whole section dedicated to finding teammates.
If you aren't serious then why are you so upset, it's just a game right? I mean you can play the game everyday winning Ip, and tokens and keys and chests, to get new champs and new skins and never once play ranked. What is so special about ranked that you just have to play it and that Riot must make the game conform to the way you want to play it, so that you aren't at a disadvantage to rank up, if you are just a casual player anyway.
I'm really not trying to be snarky, this is my first season in LOL and I sincerely don't understand why people are so upset.
