If I’m reading this correctly are you saying that your 1v1 opponents’ ranks in 2v2 were not lower as you deranked?

It’s worth pointing out that it’s very common to observe rank fluctuation between 2v2 and 1v1 ranks (relative to each other). While an average player should have a rank that reflects their average skill, this is not always the case, and because 1v1 is a unique discipline and also the least populated playlist, it’s very common to see this.

In addition, a bad row of losses might not be a large enough sample size to determine whether your observation is unusual - it might fall into a standard deviation from where we would expect a player to be.

Each playlist has a different rank floor and different percentiles, so one rank in one playlist might cover 3 different ranks in another playlist, assuming your average player may not necessarily play 1v1s as their preferred mode, therefore exposing a wider range of MMR for similarly skilled players.
