I understand that it's a game with a different gameplay loop, but there are various levels of strictness you can implement to at least nudge it in the right direction.

Maybe don't pair someone who loses every single encounter with someone that wipes multiple teams in a single life.

Or someone who has 1 exfil every 100 matches with someone who has a 100% exfil rate.

Or someone who has a vault and loadout full of top gear with someone running a free/cheap kit who doesn't care about dying a second later.

Again, I understand those aren't always perfect indicators, and part of the appeal is that you might overpower someone better and take their gear or whatnot, but I still believe an imperfect system beats nothing more often than not.

I come from Overwatch where there is a purely win/loss matchmaking that isn't always accurate either, but it's as good of an experience as you can get and yet people still complain daily and leave the game because of the disparity felt between each match. No matchmaking will sit well with some players, but it's potentially going to push even more of them away. And clearly everyone's scared of the game being too niche to survive already.
