Since the sword sister troop tree has its weaknesses and people have been complaining about them being vulnerable how about giving them something to compensate for this.The sword sisters could give a passive bonus as if they had perks or a special perk that increase some medicine skill if there are enough of them in the party or depending on the healer of the party. The story could be that they are like nurses that help the surgeon of the party. Maybe the would help the sword therefore slowing down food consumption.
