Been playing with my old friend in doubles and we have like an 80% win rate and at some point I’ve stopped getting ranked progression in Doubles. Last night for instance we won 8/10 games we played and my progression bar stayed at halfway through Diamond 3 no matter if we won or lost. Really trying to push Onyx here, so I’d love a fix >.>
This means your CSR (rank) has reached approximately the same value as your MMR (skill). Now that your CSR and MMR match, the system will try to keep them the same so that your rank acts as an accurate representation of your skill. For your rank to go up further, you will have to win and actually get better at the game.
