wtf? sasuke had been fighting everybody all day, he was not up to 100%
But lets face it, danzo was using other peoples powers, sharingans he stole, and hasiramas dna, how can people give him credit for that?
sasuke was using purely his own power, but he actually owned karin since she would do anything for him, so she is technically a jutsu of his.
also sasuke exhausted KAKASHI staight after the battle, so technically he was superior to danzo, as for shisuis eye, why didnt he just use it? now we will never know the power of shisui, since he blew it up. and if he was so despreate to survive he would have used it, holding back on danzos part is not an excuse.
my verdict: Just a little jog in the park for sasuke.
