I will have to go against you this time,sensei.
If jiraiya would have been there, its more than likely naruto wouldn't have become the child of the prophecy or the saviour of the world and all that stuff.What makes naruto so special is his will to never give up,which was created by the fact that he was left alone in the world and nobody wanted him at all,or so he thought.
Now think about this, if naruto would have felt love and known from jiraiya some important stuff that was just shown recently, for example the fact that he was the fourth's son, its possible naruto would have gone the "I am the fourth's son so i am uber awesome and nobody can defeat me cause i am his son
". Now, if he became like that, he would have given up against haku and die. Let alone the chunin exams.
What makes naruto also a very "special" character is that since he was once alone, he now understands how people that are lonely feel and thus can help them and say the correct words, for example with inari at the start of the naruto series. If he had known that he was the fourth's, there is no way he would have kept quite and prolly the whole village would have known about it. If everyone became aware of that fact, everyone would have wanted to be his "friend", just like with sasuke and he would have reacted just like sasuke did,he would have acted arrogantly and ignored them. So he wouldn't have any friends, which was shown to be one of the things about naruto that make him a hero.
After saying all this, if naruto hadn't grown the way he grew, there would be no plot for the story line. That naruto grew up alone was a smart move from kishi.
