Me and bunch of friends we always ran into the same mistake, we are qing rated 3s, but we were in shuffle queue that was too long... so we forgot about it. So solo shuffle queue pops and we take it by mistake ending up ditching the 3v3 team by mistake.
Can there be an option for when Solo Shuffle pops, but u are in rated 3s queue at the same time, get a different message, or warning, or anything... maybe you have better ideas than me.
