Susanoo is simply materialised chakra... I dont know where people are getting "Yin/Yang Release" from because it is neither. The Sharingan itself is a Yin based KKG. I think people are getting Yin and Yang mixed up with Yin/Yang release.
Lol you're neutral on your 1st point, can you elaborate on the last 2 points like you did with the 1st one?
Mokuton: Cells contain chakra but are not made of chakra, therefore certain Mokuton techs (such as Mokuton clone) which alter the users cells shouldnt be able to get absorbed. However, most others can. People think because Hashirama adds Yang Release to his Mokuton, giving it life like properties that it cannot be absorbed. But that is false.
