Ok,so I have been thinking,some of the greathest and strongest ninja in history had some sort of outside help in order to become what they are or were.Let's start from Madara and Hashirama.Their strength lies in Indra's and Ashura's chakra inccarnated in them,they were great ninjas but without it thay would'nt be nearly as strong as they were,not to mention Madara's rinnegan without Senju DNK it would be imposiibile.The list just goes on,Kakashi,Sasuke and Naruto,Nagato etc.What I am trying to say is that other ninjas who trained reallly hard like Guy deserve more admiration then the ones with serious power boost,I would put Guy and Itachi in top spots just behind So6p
Don't crucify me just thinking out loud =D
