Duo/Trio Queue
That’s the risk of going into TPvP without a premade 5. You should probably expect to lose more if you’re not premade.
This can work well, but you have to be willing to let your MMR fall to a level that your group size can support. If you usually play as a group of five, you’ll lose a lot of matches before your MMR gets low enough that your 2-3 man team can win ~50% of the matches.
Even then, team queue population is low enough that the good teams have a far, far higher win% than 50%. So you’ll probably still get them every once in a while.
Still would love to be able to join with a team of 2-3 against another team that is also made of 2-3
