Usually when I am waiting for a match, I get a message that says we were unable to find a suitable match, would you liked to be placed against players with a higher rank. I click yes. A few minutes later, I get the same message and I click yes again. A few minutes later, I get the sage message AGAIN! I already said I want to play someone of higher rank.
Actually, my preference would be I would ONLY be matched against players with a higher rank than me. Why would I want to duel someone with a lower rank than me?
