Multiple demotions because of them
If you're hovering around emerald 1, don't duo with them. you'll regret it, I'm now emerald 3 (about to get demoted) the duo booster asked me to play support. I told them I wasn't going to win lane, so they just ignore it all together while we get camped when they played jgl. then I switch to top and win lane and they turbo int all game. I honestly have easier time solo then trying to duo with multiple of the boosters they have to offer. make sure they don't try to force you into uncomfortable lanes, just tell them to leave till you get a duo you lane you want.
