I was playing competitive and I've got a Viper (female) on my team and I head a Phoenix who was omega toxic especially to Viper because she is female and girls "can't play well". So throughout the game he was more and more toxic, Viper snap...

Recently I started playing with a friend, we are 1 rank apart and most of the matches we get even 1 rank higher, why is this, why can't the game search a bit longer to give us a balanced match?
