Not true. Kakashi's chidori was only mastered with the aid of teh sharingan. And Jiraiya said Rasengan took the fourth 3 years to MASTER. If I recall correctly we have seen no proof to say that Jiraiya didn't create the technique, and Jiraiya was the Fourth's instructer.
Also we have seen Sasuke fight for all of twenty seconds. During that time he not only displayed an entire new type of mastery over the sharingan, but swordsmanship and a complete revision of the chidori. Now if you would be so kind as to explain how that equates to ONE direction?
Meanwhile Sakura has learned one attacking trick that probably wasn't that hard for her to learn (Given that she already had near perfect chakra control, and a teacher who was incredibly experienced in using that technique) and medical jutsu. And she appeared substantially weaker then Sasuke.
Additionaly Kakashi flat out said that a signature technique takes around 20 years to develope. I can show you the manga page if you want me too.
First of all, I clearly recall Jiraiya stating about the Rasengan, that the 4th created it. Period, end of story. Jiraiya isn't a modest man, if HE created it, he'd brag about it.
Second, all Sasuke did was modify an existing technique (to make it flow outward). Naruto did the same to use Rasengan (it normally is created with one hand, he uses three and a clone, it's a modification), and it took him all of a week to figure it out. Nothing special there.
Sword fighting is supposedly part of weapon training, and on top of that, we don't see how good Sasuke is with that sword of his - his skill level with it is totally unknown. For all we know, he carries it around to stab things relying on the Sharingan to avoid counters and predict the opponent's moves. Skill needed - what they teach to Genin, likely. After all, he can OMG SEE WHAT YOU WILL DO.
*smacks Kishimoto for his stupidity*
The Sharingan was bad enough when it stole jutsu. Now it's just a load of BS.
Besides, Sasuke mastered Lee's taijutsu style in A MONTH, thanks to that stupid Mary Sue-gan. I can totally see him ripping off some guy's sword style in the Sound and mastering that as well in a month.
And don't say it's impossible. He did it with Lee, despite the Sharingan having been STATED it cannot copy seal-less moves - apparently Kishi forgot his own statement...
Meanwhile, Sakura:
-has learned how to attack in a coordinated way (see when she plays possum and blindsides Sasori - and no, it wasn't Chiyo, she was down as well, that was Sakura acting - also notice her movements are fluid - she was very sluggish in the Chuunin Exam, and it was more of a catfight with Ino...)
-has learned chemical knowledge that usually takes at least 20 years to amass, and unless she's got Superman's fast reading skills (one book in 5 seconds), it's flat out impossible, she simply can't assimilate knowledge fast enough - ESPECIALLY if she's tired from a day of training. Ever tried studying when very tired? I did. It's impossible. Forgetfulness, mistakes and bad grades are guaranteed, no matter how smart you are, because the brain's too tired to store information properly.
-has learned medical jutsu good enough to revive small animals. Notice how most medic nin have to concentrate to simply heal light wounds. That a barely-chuunin like Sakura can REVIVE, no matter how small the revived being is, is just plain stupid. It's like having a fresh graduate off senior high school treat cancer successfully.
Granted, the above may simply mean Kishimoto doesn't know jack about chemistry and biology - in which case he should DO HIS RESEARCH. Otherwise, he just draws a manga based on bad fanfiction. Research is important when the setting does not have bullcrap like a Dragon Ball set to auto-revive people...
Where does it say that he doesn't have any time? Is it possible that it's Naruto who didn't go looking for help instead? Or maybe he did try to help, but Naruto couldn't absorb that knowledge because he's too busy doing something else, like pranks? (Remember - this is the Naruto who couldn't do a simple bunshin. Why this is so, we have no real idea.)
He's an academy teacher and has several classes besides Naruto's to teach to. And if you think a teacher's life consists of free time after school hours end, think again. Who do you think checks homework and gives marks to tests? Elves? I'm sure that my old math teacher would be delighted to meet elves who can correct the homework and the class tests... she always used to moan about never having free time until late in teh evening due to the mass of tests she had to grade every day.
Now, regarding a little process called "Delegating". It's when you have lots of people who can help you do things, and you let them do their stuff while you do what only you can do.
Please don't tell me Tsunade has to run around the village each day helping damsels in distress. Konoha has a COUNCIL - something that cuts the amount of workload that Tsunade has to do directly by a significant amount. True, that Tsunade still has work to do (as seen in different times), but WHAT does Tsunade actually DO other than paper pushing?
That same council is full of power-hungry, untrustworthy individuals who have pushed many times in the past to have Naruto executed or at least exiled.
Tsunade isn't stupid, and cares about Naruto. I doubt she'd just let the Council handle any halfway important matter, just in case they pull something stupid that'll cause her no end of grief.
Also, the Hokage was the one who distributed missions over the day, in case you forgot the scene where he gave the Wave country mission to Naruto's team. And after a disastrous invasion, missions bring in vital money to rebuild - Tsunade herself stated she was stretching the jounin and even chuunin thin to take as many missions as possible when she sent Shika & co. after Sasuke. And this presumably lasted at least one year, if not more - you don't recover from what amounts to full scale war and extensive damage with loss of life in a snap. Look at the Sand - it was stated to have fallen in misery after a war gone wrong, and after YEARS they were still struggling.
Tsunade had her work cut out for her, and even pushing papers is like taking a drop off an ocean.
Who's to say that she does not have experience in such learning conditions? She could be helping out in the ninja hospital daily as part of her training, and as a medic nin's apperentence, she'll gain valuable experience in real life situations - NOT just book smarts.
Working daily on patients would give her the edge in knowledge and experience that training (like with Lee) would not give her otherwise.
So you'd trust an inexperienced nurse in training with patients who could well return home with cuts, stab wounds, bruises and internal injuries of life threatening level? Remember, those are NINJA we're talking about. More often than not, they're going to return home in need of serious treatment, unless they're lucky.
I don't believe it's too fast, especially when every second counts - and they KNOW that.
Have you ever been in a situation where it is literally life and death between one minute and another? That's the kind of life Sakura (and Naruto) is living. They know that if they don't spend their ever waking moment getting stronger/better, they'll lose Sasuke forever (though WHY they would want him is completely above me...).
That goes for every ninja in the village. They're NINJA. They could DIE themselves if they don't train to their best.
Yet I see no one else making as much progress as Team 7. So I guess they don't care about being killed, or having their teammates killed, eh?
Add to this that it's a war situation in Konoha right now, what with the Sound looming at the horizon... I could understand if EVERYONE made as much progress as Sakura - after staring death in the face between the invasion and teh Sound 4, it'd make sense to get serious - but so far, what we've seen is the same Team Gai, and a vastly improved Team 7... even though both Neji and Lee seriously risked their lives in the chase mission.
I suppose they failed to learn the lesson.
...yeah, even I can't believe that.
Ah. Who said she's been doing taijutsu practice? We haven't seen her in any forms of taijutsu (have YOU seen her use the Konoha Whirlwind?) at ALL, so we can't assume that she's been practicing taijutsu - and her super strength is NOT taijutsu, before you start.
Her Chuunin Exams wouldn't have intrupted her training if it was PART of her training. Medical studies and practices can easily be one thing if she was working in the hospital, so I don't see where the division of focus is (even though I can see why you'd feel she's stretching herself thin).
Taijutsu is hand-to-hand fighting in general, not necessarily an OMG SPECIAL FLASHY MOVE. The taijutsu basics are what even Naruto worked on in the timeskip - he is less of a brawler and more of a refined fighter.
Sakura used to catfight, not 'fight'. The fact she can actually attack in a fluid and coordinated way proves she's been training in taijutsu, at the very least the basics.
Actually, it's entirely possible that Sakura was taken off the active ninja list to train solely as the Hokage's apprentence. Kakashi was obviously reinstated as an active ninja and given missions (it would not make sense to leave a perfectly trained and well ninja like Kakashi when they're short on people etc). That meeting 3 years later COULD be their first reunion in all those years (Sakura being too busy and Kakashi could either feel guilty or too busy as well).
And she made Chuunin how? Only active ninja can take the Exams. It was stated more than once. In fact, I'd bet it's why Naruto is still a Genin - in order to be allowed to leave this long, even with Jiraiya, he'd have to have been taken off the active duty roster. Otherwise, he'd have been branded a missing nin.
Sorry if I come across as hostile, BTW. Teeth hurting, have a hard time staying calm. For what it's worth, I'm not mad at you, I'm mad at Kishimoto.
EDIT: polished the post. Too many typos. Typos make Hulk sad.
