The only reason Kabuto got hit, is because he got very cocky.

And, guess what, fighting Tsunade has gotta drain your Stamina and your Chakra, he would've been able to heal, if he was at full from the start.

And saying that "oh, he only survived because of his regen" is bullshit, its a damn hard technique. Naruto only lived past the Haku arc because of the nine-tails. And I don't see anyone complaining. Hell, Naruto should've died right there, right then after Kabuto hit him, he had to be saved.

Also, the whole deal with Sasukes evolved sharigan. I think the manga overexagurated its effects. First off, Sasuke was able to see and predict movement before, its nothing new.

Zabuza would own him, plain and simple. Please, give me some facts on how Sasuke would beat him.

The gennin's aren't weaklings, but they don't compare. The difference between Kakashi and Itachi fighting, and Itachi and Sasuke, well, basically Itachi kicking the shit out of Sasuke for a while was huge.

Kakashi held his own quite nicely, he took a few shots only to save Kurenai, and only lost because of the Mangekyou. Itachi only used the mangekyou on Sasuke for torture purposes.

Funny, even if a TEAM of Jounin were needed to stop the sound 4, they looked pretty damn whipped after fighting the 2 jounins. Lets take some more quotes.

"We lose too much strenght when we fight at curse seal level 2"
"What troubles me most is the fact that we can't use our bodies"
"There wasn't any way agaisnt two Jounins... If we tried to conserve our energy, we may have been defeated."

Sounds like it was easy fighting 2 drained Jounins. So, 2 drained Jounins fight 4 sand nin, lose, but force them to use enough energy so they can't use their bodies, and go curse seal level 2, then immediately after fight Naruto and Co. inbetween running like heck. Also, Naruto and Co got Food Pills off Chouji.

Oh, and I didn't see anything about needing a team. I saw, "if you follow them, you will end up dead" but that was to a fellow Jounin that was with them, just as low on Chakra.
