reread hashirama vs madara and you will see what ps defense is capable off. unstabilized one tanked tbb by full kurama, hashiramas buddha hands were required to break open and remove ps armor and those hands had impressive dc. sasukes ps is superior to Ems madaras and considering its attacks tearing through meteors which dwarf several mountain ranges, its defense should be at that level or even hgher. ps cant get destroyed by something weaker than its own offense. its not rocket science, soosano defence is no joke, let alone a perfect soosano made by a guy with half of hagoromos powers.
OT. lava frs gets tanked low dif, same with that 5 tails attack which didnt do any considerable damage to kaguya, only knocked her back i think. 2 bdrs should damage it considerably to the point of nearly tearing it off, and destroy it. thats the only attack naruto has shown that can destroy it, any other attack is getting tanked. its high time people lay off the naruto wank
