@Sand_spitter 12% win rate is still crazy good. All other things equal, most players should expect a win rate of 5% in Trios (1 out of 20 squads) and 3.33% in Duos (1 in 30 squads). I'm a below average player who plays only pubs and my win rate is about 3.5% and that's where I'd expect it to be.
SBMM is still complete crap though. I should never be matched up with or against high ranked players but I regularly am. It is no fun for me and I can't imagine that having a trash can like me on a pred's team is very fun for them.
