In a story world where what generally happens (in front of the camera) is that people are adventuring and hitting each other with shiny metal sticks, a 50-50 gender balance would feel forced and generally detract from the quality/believability of the story. Kudos to Rich for the (IMO) pretty ideal gender balance in OotS for the type of story.
