I agree with Rage gtx.... it's for the very same reason Orochimaaru was using cursed seals inorder to bypass the weakness of his "weak" body. To be honest when the series was going on I thought kabuto(with modification, Edo and WZ) would become the strongest villain who would be defeated by Team-7.Orochimaaru finally realizing his mistake after coming out.And returning to leaf with sasuke. And besides that healing seal which tsunade and sakura used is not something one can underestimate as it did save most off the shinobis(before Naruto gave them powerup).It's more powerful than regular SM or curse mark(the only way I see of beating it without biju's power is continuous SM or orochimaaru's immortality). For Naruto.. I thought they will atleast teach him some of his father's technique or skills(especially during that 3 year gap) or some nature transformation[apparently no one [parents or teacher] taught him this]he could have gained a cool earth or water jutsu to counter sasuke's fire style and so on.
