Ranked Input Selection Limited to Solos/Duos Only

Hey team! Great work on the launch, and huge thanks to letting us dive in a whole 3 weeks early! I understand that this is a ‘beta’ and some features and settings might not be available until the full launch, but I’m confused as to why you are only allowed to select a specific input for ranked lobbies in the Solo/Duo playlist? This forces me to either a) play solo and hope that my teammates have open mic so we’re not at a disadvantage or b) play against controller where I’m guaranteed a disadvantage. It would be ideal if I can select keyboard and mouse only lobbies with more than 1 teammate in my fireteam.
