naruto using kyubi chakra is the same as itachi using sharingan [img]i/expressions/face-icon-small-tongue.gif[/img]

ok now im serious. naruto depends on the kyubi chakra when he himself is too weak to defeat his opponent i think this is okay since he is the main character but sucks so he needs something to make up for his own sucky-ness besides it would be even more stupid to know that he had the kyubi chakra there to help him but didnt use it.
