She's mainly a support Nin. She has combat abilities, but it's not her thing. Battles can't just have people capable of the front lines. There has to be support as well. I don't like her and all. But I'm not blind to not know this.
Stop thinking about boys during the battlefield, especially in front of a God like Madara.
It has nothing to do with her power. She is mentally retarded, and last I checked if you had problems with your mental state, you shouldn't be on the battlefield fighting, because you will just put everyone else in jeopardy with your selfish inconsistencies.
Because she isn't unfit for battle.Healers are just as dangerous in fights.Sakura is the strongest teen female ninja of all of K11 therefore if she is unfit that would mean you will have to ask all of the other girls to stay in the kitchen too
