It's a good story the way it is, I'd probably just leave it original. If I had to though I'd probably add more fighting time for Guy and/or Lee. Every story will have some kinda plot hole, you would create another plot hole trying to fix another.
Naruto's obsession with Sasuke
Obito being alive he's my favorite character but his existence defys all types of logic he didn't have kamui so how did he survive the rock slide? And also why is it that his eye didn't get crushed along with the other half of his body?
And Sakura she would never exist
-->Get Naruto a crush on both Hinata and Sakura so things would get more interesting.
-->Nagato shouldn't sink Jiraya's corpse so he could be reanimated.:scorps:
-->A special manga edition showing the making off of Kurenai's baby, if you know what I mean. :snick:
-->Tenten needs more pannels.
