Hello, I am sorry to say, but there is a lot of different cir*stances that go into the matching for events, level being one of the major ones. If you are currently at max level, or near it, it is far harder to find opponents that are below your power level, especially if lower power levels do not participate. Many players have an idea of when there are typically less high power players matching, you could always ask your fellow players when they think it would be a good idea.
