I bought a solo boost for Flex, the first thing the Booster asked me is "Can you buy me Darius?" which was kinda baffling since I mainly play Assassins and I've got 0minutes on Darius... and this dude was gonna take him straight to ranked. I asked him if he could play any assassins since I don't ever play champions that are even relatively close to Darius, he lost 2 games on my main and then just picked Darius regardless. I quit the boost before he could finish it, because I don't want to get banned.
