I see people calling Tsunade, Sakura, Ten Ten, Ino and many other female ninjas useless, but nobody says anything about Kushina Uzumaki.
Don't get me wrong, Kushina is awesome, but in all honesty she never did anything. I doubt she'd even graduated the ninja academy or learned any basic jutsus. She was so spoiled by Minato, she literally didn't have to do a thing, it was all on Minato lol. She'd never worn a ninja outfit or gone on a mission or fought in a tournament.
