Why should I be penalised for my teammate leaving in comp? I lose double the rank as I do gain when I win. Just do what LITERALLY EVERY OTHER competitive game does, and remove the ability to leave mid-game. Remove the ability to switch character or return to orbit during a comp or trials match, and develop AI to take the place of players who left. Again, like many competitive games have done. This AI feature can be used in normal PvE content too, say, if your awful servers causes someone to disconnect, and the team needs a placeholder until they can re-join. After all, nothing more infuriating than your awful servers disconnecting me or my friends at wave 47 on Legend Onslaught and not being able to rejoin.
