Hello! Sorry to hear about your experience. The reason for such an issue is an imperfection of our Matchmaking system: due to the flexible balance and abusers who are trying to find loopholes in the system, you can be paired with or against inappropriate players. We are actively working on the adjustments for the system, and more tests are yet to be completed 👌
At this moment, we recommend shuffling your Hangar a bit and teaming up with your friends who have approximately the same SP as you. Try to make Matchmaking work for you!
