For me it's basic. If she is a medic she is useless. Period. There is no proof that someone in another village isn't their village's version of "tsunade". There's no proof that there is another female in the alliance that is exceptionally good at medical jutsu. It cannot be proven or disproved, so as it stands she is not useful or useless. I base this off the fact that there are too many females in the series that are medical ninja. If being a medical ninja was a rare skill, then I would agree that she is useful.
But, because kishi made it clear that 70% of the femlaes in the series are healers, then her job is "mainstream" and therefore uninteresting, bland, boring, cliche, regular, , stereotypical, commonplace, platitude, dull, stale, overused, tiresome, and etc.
My whole problem is that she is exactly a medical ninja. If Kishimoto has the NERVE to call anyone a main character, then he better back it up. She better be on the same level as naruto and sasuke.
If not, then she is automatically useless. Nuff said.
If she can't jump into a battle, and help, then she's useless. Nuff said.
If she doesn't have the resolve to do what is necessary to protect the people she cares about, then she is useless. Nuff said.
If she constantly cries, then she is useless. Nuff said.
If she can't even lend help to the main character in the form of encouraging words, and yes I'm talking about chapter 615, then she is useless. Nuff said.
Nuff said. Nuff said. Nuf said.
I'll say this again, if she can ONLY heal, then she is useless. If she only has the overused stereotype of super strength then she is useless. Either kishi gives sakura, her own unique skills that is only unque to her, or she will be delegated to the background as a side character. Nuff said. So yes, sakura is bashed for doing her job. She should not be a medial ninja in the first place. She should be her own unique woman, and an example of a strong female with excellent character development, but that is not the case. She should be "sakura", not Konan, not tsunade, and not a medical ninja. She should be unique to "her". Her skills should be rare to only a few people, or completely to her.
Naruto, Jiraiya, Minato, & kakashi & konohamaru were shown using rasengan = rare skill. You don't see thousands of men doing this technique. Kakashi & Sasuke using chidori = Rare skill. You don't see thousands of men using chidori. Sakura, karin, tsunade, rin, and thousands of other fodder females using medical jutsu = Mainstream skill. It's not interesting or useful because if sakura dies, then shizune or some other fodder females can be trained by tsunade to take her place. Shizune was taught by Tsunade and she's already better than sakura in pure medical focus. So....
*If sakura cannot prove usefulness in ways that does not fulfill stereotypes, and overused cliches, then she is useless 100%*
This is not an argument...this is a fact in my opinion and it's not changing. This is just my view so don't get your panties in a bunch lol.
