Team1 has mmr disadvantage due to party size. Parties are matched against higher mmr ppl for fairness.
That’s why Team 2 has Plats and fewer Silvers.
You didn’t specify which team you were.
The usual gain/loss is 200 points. The extra 22 loss indicates that this was not the first lose, and that your team probably was the favoured one (the one expected to win).
I was team 1. Even though we were a 4 stack vs 2 stack they have a serious MMR advantage. I’ve never seen it this high before. Normally when that happens we actually lose less points.
Blizzard does not understand matchmaking. The group with the plat 2 and silver 4 should have all been treated as they were plat 2. This is the prime formula for boosting in this game and its absurd.
