I'm gonna give this to the 11 high-difficulty. I would say low-difficulty but we are forgetting curse mark! As we can clearly see his jutsu are enhanced greatly with curse mark activated, and he can fly. Who can fly? No one. Shikamaru's shadows can't take flight. TenTen could shoot projectiles, but sasuke could use Katon and melt them mid flight. He could spread Chidori Nagashi or Kirin across the battlefield. Sasuke has EMS which cuts down the chakra you use one Sharingan Jutsu, and Orochimaru would have taken steps to make sure sasuke doesn't get poisoned, being his new body and all. So i'm almost sure he has anti bodies. Susano'o could protect sasuke against most attacks. While there is lighting swarming the battlefield, Sasuke could use Amaterasu to make things worse. He would definately eliminate atleast 2 or 3 of them.
But what happens when fatigue sets in? Curse mark is gone, strategies become faint as time progresses, and chakra is running low? Plus, Kiba can follow the blood from his eyes and Neji and Hinata know where he is 24/7. You still have 8 or 9 Chuunin to go up against who are close to, if not, Jounin level.
Excuse my crap arguement, I'm just saying. Sasuke is devastating no doubt, but every one has limits. Cept for Naruto. C;
He would eventually fall.
Things might be different if he had Suigetsu or Juugo. But he doesn't. Flame me, de-rep me, do whatever. It's an opinion that doesn't offend and we all have one.
