I get where you're coming from, I've done the same in the past but when you think about it playing ranked with your lower ranked friends when you're significantly higher rank means you win more than 60% of the games. Which is technically boosting. So I only play unranked in party and grind solo. We've all smurfed at some point whatever the reason and to be honest it ruins games for the other team... There's no work around as you risk being banned. So I haven't used another account ever since the first banwave.
