In what category?Kishimoto stated that he wanted Sakura to be like a realistic girl. That's why she doesn't seem to fit into this manga, it's a manga about shinobi and she seems out of place. Sakura's probably just meant to pull in the female side of the fanbase.
All the ninja in this series have had mentors. Not only Sakura, there was nothing wrong with her asking for help from Tsunade, that was actually one of the few good things she did in pt1.
She stated the reason that she wanted to become a shinobi was to become strong and have the ability to defend herself early on in pt 1. She knew she was weak and useless, but she wanted to change that. It's a simplistic goal in comparison to the likes of Naruto and Sasuke, but then again Kishimoto stated that he wanted her to be a regular girl. Nothing about her is meant to be too complex when involving her back story and past. In an interview Kishimoto even stated when asked about what her backstory was, that she was a regular girl and there was no use on elaborating, because we are all normal people.
She liked Sasuke in pt1, as did nearly every other girl. Every girl in the K11 liked someone, it was annoying but you cannot hate Sakura alone for it because they were all like that. Atleast she pretty much dropped that side of her in pt2 and you nearly never see it now.
Because I've never seen a regular girl to punch the ground and leave crater.
