As we all know that, that the Rinnegan Nagato used, all shared the same visual link correct?
Say we had the 6 paths of pain in combat with a genjutsu user. Say that the Genjutsu user cast a genjutsu on one of the paths of pain. Wouldn't this effect all of the 6 paths of pain? Since they share the same visual link, all paths of pain will be effected by the genjutsu... as well as the original user. Nagato would've been affected as well, if someone threw a genjutsu at one of the paths of pain.
I believe Madara effectively eliminated that weakness. Since the rods are not shown within Madara. Does this mean Madara does not share the same visual link that Nagato had with his paths of pain?
