It used to be that way a few years ago but as Dragon stated people just began abusing it and stacking an all Lefty lineup and it would take forever to find a match bc everyone would just back out of games if they saw you had a lefty... I don’t think you can give someone an L for backing out at the lineup screen so that’s not a solution. I’ve had to back out for a number of reasons especially like accidentally forgetting to change my lineup over to my ranked squad and entering with a conquest/challenge lineup.
