Hate the new matchmaking..
Really ridiculous when your best role is mid and your other roles are meh and out of 20 games of having mid as my primary pick in ranked, I've gotten it ONCE. It's actually very stupid and it makes getting out of lower elo 10 times harder when you're playing on a role you aren't very comfortable with. Had a way better chance at getting mid when I was a higher pick. I understand that your idea was that people would get their role much easier but it's honestly broken. IE: I was tired of getting top so often (because that's my secondary role that I'm slightly comfortable with) so I put my primary as mid and my secondary as ADC (Bottom). My friend who is an adc main put his role as Bottom for primary and Top as secondary, yet again I was forced to ADC and he had to top. It's ridiculous how the bigger majority of people won't get their primary because of literally one person. I've tried this out with 3 que and 4 que. Your system is broken and it's rather irritating. At least fix it so the MAJORITY of the group get's their primary role not just a random chance which typically happens to be the one guy who screws everyone over and makes everyone take their secondary.
