It does weird math on some of those to fill in the gap on giving someone hero. Losing team can also have just 1 hero. If a team is so bad you can get the only badge. Some of those are really easy to cheese in a game.

Playing BR1 (almost always uptiered to BR2…) I accidentally get best medic all the time because my medics are my only “assaulter” squads. Also builder/engineer are almost inevitable since 9/10 games i’m the only one, or one of 2 people, who build rallies.
