I love the idea of battle sisters. How many times in medieval lore have you seen the badass archer remove their hood to reveal a woman….. Or that big ginger woman who runs the local pub that can manhandle the most burliest drunkard?
Women can be nimble and quick which means high initiative. Often good supports due to their soothing/healing/nurturing nature. Support skills are usually so dominant that they can sway a losing battle. Think skills like captain/rally the troops, both op skills.
As I said before it should be realistic and not some half-naked 20yo with DD’s and a enchanted greatsword. XD
