I think a player rating system in the vein of MMR would be the way to do this, but I also think the playerbase is so small (particularly in my region) that it’d have to be so loose that it’d be ineffective in order to keep queue times reasonable.
I don’t think hard-set gates like player or gear level are a reliable way to do it, in any case.
TBH I think it’s mostly a non-issue. It’s as impactful and frequent as having a speedrunner on your team and the general reaction to that is “suck it up, princess”.
