i'm just wondering cause well the knuckle head is unpredictable for example when naruto stole that scroll back in part1 and learnt multi shadow clone jutsu what if he learnt all the jutsu in that scroll and hasn't said shit cause he's been saving it for a worthy opponent/opponents like either obito,madara or sasuke cause well the reason i say this is because he obviously has some powerful jutsu or sealing tec up his sleeves why jiraiya and others have been concerned about naruto using THAT JUTSU but the question is what is it and why hasn't he used it yet.
Naruto stole the scroll just for passing out the examination. He himself said it took so much time just to master one jutsu. He wasn't getting any time for learning other jutsus.
Most important, at that time he was not knowing about the villains like Obito, Madara, Akatsuki members and the main Sasuke.
He faced terrible situations in part 1 as well as part 2, then why do you think he was not using those "so called jutsus from that scroll" that time. He was also unaware of the Fourth Great Ninja War.
Naruto is a knuckle head who takes a long time to learn jutsus (if shadow clones are not used). Then how will he use the sealing jutsus all of a sudden during the war.
Whenever Kishi decides to upgrade a certain jutsu, he gives us a hint (Like how Naruto tried the Rasen Shuriken once again at Myoboku so that he can use it while fighting Pain).
Kishi never brings out any epic technique directly on the battle. (except the techniques of shinobis from other villages and the experienced shinobis of the 5 great nations).
Kishi always gives the incomplete versions of the techniques to shinobis of young generation to start with. (Like Naruto's first shadow clone technique, Sasuke's fireball jutsu, Shikamaru's shadow paralysis, Choji's expansion jutsu, Shino's bugs, Kiba's Gatsuuga, Gaara's sand techniques, Kankuro's puppet master etc)
Conclusion : Naruto's pockets are empty. Naruto don't have anything up his sleeves otherwise Neji could be saved. And lots of shinobis' lives could be saved.
