She was partnered with the elite elder of Sunagakure, Chiyo-baa sama, and played a huge role in bringing down the strongest and fiercest ninja of the Hidden Sand, Akasuna no Sasori.
She concocted an antidote to Sasoris poison, which an entire village failed to do, including Chiyo-baa sama, and was also thought impossible by Sasori.
She saved Kankuros life with her unique medical techniques.
She is the medical ninja in Team Kakashi and she always does her job well.
She healed many people during Pains invasion, possibly saved their lives.
If she hadn't decided to take down Sasuke on her own, prompting everyone to chase after her, including Naruto, Sasuke would still be willing to kill everyone in Konoha, and Naruto woud still have doubts about his friend and his decision.
By doing so, she also saved Karins life, who was about to be killed by Sasuke.
Sakura was the only one who tricked the greatest trickster in the war arc, White Zetsu, took him down and deciphered his abilities. Thanks to which, Zetsus origin was discovered by the Shinobi army.
And she will most certainly surpass Tsunade if she hasn't already.....
How is she useless? Hate much?
