How cool is it when u have auto-filled bot lane vs duo q boosters?

Literally have over 10k gold lead lasr game and lose cuz someone is learning tristana and keeps pushing the wrong button and jumping into their team. Who the fuck picks tristana when they get auto-filled btw??? As though thats the easiest adc to be useful on lol. Such a fucking troll matchmaking when 3 of the people on ur team have S in end of game but ur adc does less damage than a lulu support smh smh smh. Plz no more auto-fill to adc. jesus rito
