Bungie already said that solos and duos make up the vast majority of the playerbase. They are the reason it works. Splitting them away from everyone else would probably hurt both groups in terms of queue time and match quality. Yeah, you wouldn't match teams. Great. But your odds of being dragged down by a blueberry who doesn't shoot anyone stay the same, if not increase. Is that really an improvement? They're gonna test it in labs, but we'll see. I think there are much better solutions available. Just off the top of my head here, what if they applied SBMM to [i]only[/i] solos and duos. (Players in a full squad could match anyone, either a team or solos/duo close to their skill level.) Yes, they'll still be able to match teams, but they'll be guarenteed team members and enemies close to their skill level. This would make solos an actual threat to teams, make matches more competitive for solos and duos, and increase solo/duo win rate from 30% to 40-50%. An obvious drawback is carries done by duos plummet, which is against Bungie's "friendgame" philosophy. Just an idea though.
