In this game in public matches the higher your score (spm / kd) consistency, the better players you get to play constantly solo. Teams of often. So yeah, not a game made for people who want to win solo or in small parties constantly. If you really care, you would need to join a clan or only play in full parties.
I would recommend joining rooms of as many friends with lesser stats as you can. Just start adding people with average and below average stats. In any case your w/l is highly party / team based & you’re generally only 1/6th of a team anyway. I have 10x times higher ffa win / loss ratio than kc / dom in this game. BS stat for solo players while you also get dropped in lost games constantly.
You can’t win games by yourself constantly on this new SBMM system, it was hardly convenient on the old system with or without a few buddies let alone now solo. It’s a pointless stat imo. I would stop try-harding and just play the game for fun, if you goof around long enough you will get to play better, less connection based lobbies without the host dashing constantly from my experience. The normal / average lobbies. Same for when joining people with average and below average stats generally.
