[2019] why do i always get unranked lvl 60s as teammates?

Just to jump in, your clearance level has nothing to do with matchmaking. Matchmaking is based off an MMR system. Clearance level is just basically showing how long a player has played the game for, it does not get factored into matchmaking.

But thank you for your feedback regarding Siege's matchmaking. When you mention "1v5/1v4" are you saying that you are fighting against 4 or 5 enemies due to other players dying? Or playing in a partially empty squad? That is a separate issue that has been reported.

Thanks for the suggestion. We are always monitoring feedback and suggestions surrounding matchmaking.
