First of all she has basically no redeeming personality traits in part 1, and very few in part 2. She has contributed very little to the plot compared to even some side characters. The entire concept of NaruSaku has been 100% debunked in canon since Naruto rejected her.
To put it bluntly, why is this character still alive?
It's almost obvious you just hate Sakura, but at least you got some points, but... there are few I won't agree:
a) She has matured
b) She didn't blush anymore on part 2 looking at Sasuke, not even when she found him on the bridge, nor in Orochimaru's Lair. That means she isn't the silly girl who was sick in love with him.
c) She has the ability to command the Konoha's Medic Unit in middle of a war instance (Pain's Arc)
d) She was the member of Team 7 who less chakra reserves had. Now she can heal without wasting chakra even if she isn't a chakra monster like Naruto... Her training gave fruits.
e) She surpassed Shizune in chakra control, when Tsunade stated that Shizune was a learning machine when in came to chakra control in middle of Sakura's medic training
f) She had the balls to keep the training with Tsunade, that is, she got determination, something she hadn't in part 1
And... sorry, but the manga is about Naruto, he is the main factor, he is the main asset, Kishimoto is a sexist, we are in middle of a war to protect the Jinchuurikis and the world (part 2 is about this). There is no space for pairing.
