I commend you for the effort and I agree whole heartily. Details were a bit excessive but I'll handle replying.Sakura has already had a crap load of developement...compare her to the trash that was Part I Sakura!!!!
First of all she played an important role in defeating SASORI...the guy killed the Third Kazekage known as the strongest Kazekage.
Also, she has become more than likely the greatest medic in the war (considering how Tsunade is down at the moment).
She had her greatest moment of resolve when it came to the whole Bridge where Danzo died....She tried to kill Sasuke, but couldn't...and in those moments decided to take the role a medic does in any situation...she is going to be there for both Naruto and Sasuke in whatever they end up doing.
During the war she told Lee and others how Zabuza could penetrate the Manji defense formation, and later one probably one of the MOST IMPORTANT aspects....when the Neji Zetsu screwed up SHE CAUGHT THAT...some people would've just tossed it by, but not Sakura. And then she managed to take Yamato's intel along with this new Zetsu, and finally allowed the alliance to discover the true terror of Zetsu's power.
Sakura is a medic not a fighter....and this fight is far from over.
She has already healed Kakashi which bolsteres the fighting force that much more. On top of that we still have Shikaku's strategy....which Sakura could easily play a huge role in!
I can understand your frustration....she deffinatly needs more to be a true Heroine of the series....but Kishi doesn't do well with female characters as he said.
I'm a Hinata fan personally so I'm enjoying this little bit of spotlight she is finally getting, but Sakura's developement, while not as good as it should have been, has still been overall greater than any other female character.
She went from a useless fangirl, to a competent fighter, an amazing medic, and someone with a real sense of confusion in character (loving Sasuke who is basically an enemy).
Seeing as you have respect for other people's feelings is most commendable. It's hard to find a person as yourself to respect other peoples views without the need to insult there faces. Not only did you explain it in a calm matter you even state in a personal way. And that's commendable. Nice reply.
