Right now it seems that rating gain/loss only takes into account individual mmr. If this isn’t the case correct me, but it would make more sense for it to take team mmr into account when deciding rating gain/loss.
If you’re with players that have an mmr fairly lower than yours, and you lose, the system punishes you and you get more rating dropped. The system expects you to carry every single match to progress, which is just silly. It says “Well, you lost against a team that you should have beat.” But it’s only taking into account you as an individual player, not the rest of the team. Based on individual mmr, yes, you should have, but not everyone on the team may have as high of mmr as you, which I’ve noticed happen a lot recently.
So if this isn’t already the case, this should be considered.
