Personally, I would be interested in exploring some form of handicap system. Something similar to light level advantages, but tied to your skill instead. The lower your skill, the higher your handicap. The higher your handicap, the higher your "advantage". What your "advantage" actually is could possibly be tuned per match based on who is in the lobby. In theory, this would allow all playlists to use CBMM and then it's just a matter of which ones enable the handicap system. They could even make every casual playlist (everything but comp?) have the option to use the handicap system or not (think firewalled haunted forest). This would open up all these playlists with their different game modes to be played how you want. You want pure CBMM? That's cool, go in and take your chances. You want more skill balance? That's cool too, select the handicap option and go have fun. The goal of this is to allow for CBMM but yet not have the top tier steam roll lower skilled players. Realistically, there would probably need to be some level of SBMM within the handicap system in order to prevent drastic differences. There's no point for someone with a 4 KDA to vs someone with a 1 KDA. Top tier players who would be against something like this are just those who want to steam roll lower skilled players and have no desire for competition. Would higher skill players still dominate lower skill ones? Probably, but hopefully they would have to work for it a little instead of sleepwalking through a match and hopefully the lower skill players will be able to contribute to their team. If top tier players just want to reduce time finding a match and lag then I don't see why they would not be interested in exploring something like this.
