Over the past few weeks we’ve been reviewing reports from players about how their SR gains after a win appear to be lower when they play as a support. I wanted to share some of the results of the investigations so far and clear up some community misconceptions along the way.
...
The calculation of your SR adjustment after a match doesn’t look at your teammates, but instead compares you to the performance of other similarly skilled players with that hero across an enormous pool of competitive matches. So, we compare your Genji play to the play of other Genjis, Ana vs. Anas, etc. Since we’re comparing “apples to apples”, we shouldn’t see any kind of support specific bias in SR adjustments due to player performance.
We’re still seeing anecdotal reports of some players experiencing lower SR gains on wins, but we’ve also been seeing other reports from other support players that their SR gains look correct. Based upon our investigations so far doesn’t look like there’s a broad systemic issue affecting all supports across all competitive matches. There might be a more localized issue affecting a specific hero, or a certain type of play style or game situation. It also might be something completely unexpected, so we’re doing a thorough examination of all the code that affects SR adjustment.
