Theory: Susanoo only weak against physical attacks

[9Bijuu]

Itachi defended himself with the Yata Mirror his Susanoo was holding. It would have utterly obliterated his Susanoo, he just used the ultimate element-blocking shield to stop it. We've seen Susanoo broken twice by taijutsu and it was from the top two most physically strong characters so I'm going to have to disregard this theory for now.

i think it's tht close atacts can get around the ribs and through the spaces,

Madara just absorbs ninjutsu so his is.
