It just occured to me that simply because the Rin'egan is the most powerful of the three eye techniques doesn't make the user invincible. Afterall, Shodaime without any eye bloodline limit was able to defeat Madara, and Chiyo Ba from the Sand also talked about how you can fight someone with the Sharingan. It seems to me that Naruto may finally be heading towards a climactic battle which is more than just 'power levels' but may actually involve some strategy and plotting,
