Also, breaking/dispelling illusions and the 'safe' limits of the demon fox cloak and what triggers it. Additionally, there are a few minor things that haven't been discussed in series, but that I felt Naruto had improved at. Notably, his Taijustus has seems stronger to me then it was pre-skip.Originally Posted by Pandadice
Also, one thing to remember is that it was stated at one point that it took the fourth 3 years to develop rasengen. Under Jiraiya, in the same time of 3 years, Naruto developed a new version without using Kakashi's clone training method. So I don't think we can really trash Jiraiya TOO much as a trainer.
