I have the same problem, I'm gold two, but when I search for an opponent, I need to try three of five times, to find a opponent, and when I find somebody, in the almost case the opponent are Diamond one or two, so I don't have a opportunity to defeat his team.
I play this riff battle between 22:00 and 0:06 UTC-6, the problem is, he lost in some nodes, but the game don't count that, only count when he win, so he can win more points at the end of the riff battle
