Team leaders are designed to lose and NEVER achieve their goals.
Why not? I love endings in which the good and bad guys both win, one good example is ......MGS4...... (to help you not get spoiled, it's a PS3 exclusive released in 2008 and it has 15 characters in its title and 17 in its subtitle). I like the type of antagonists that I find myself agreeing with and/or who actually wants the same thing as the protagonist but in a different way.
Adding a female leader would change nothing. Except giving the relationship-less trolls to make pokegirl topics about them and wallow around with their sexually promiscuous drawings and counter your points about needing a "women in power".
I love the way you describe the hopeless who have "<Pokégirl> is my wife" in their signature.
