What attacks do you believe make it through Rotation?
What about?
Bijudama (And Variants)
PS Slash
Shinra Tensei (And Variants)
Shinsuusenju Barrage
Rasengan (And Variants)
Asajaku
Hirudora
Raikiri
Sakura's CE Hyakugo Punch
Kirin
Toad Blade Slash
And others, but I want to see what you think about these
Only powerful drilling forces that can counteract the spinning chakra can pierce a rotation and also any supermassive attack that can cause the chakra to collapse under the weight could break it. The size and strength needed to break it is determined by how powerful the rotation.
As for your list (this is for the regular rotation):
Bijudama (And Variants) - No This classifies as a supermassive attack that could literally crush the user under a massive amount of exploding chakra
PS Slash - No, this is also classified as a supermassive attack as well
Shinra Tensei (And Variants) - it could only counter the smaller varients of it. The large variant of it is considered a supermassive attack
Shinsuusenju Barrage - Again, another supermassive attack
Rasengan (And Variants) - it can defend against only the smaller variant of rasengan because rasengan is a drilling typoe force that also uses very dense and rotating chakra that could counteract the rotation of chakra in rotation.
Asajaku - Yes, rotation is capable of defending against virtually all taijutsu attacks
Hirudora - This one is a bit more tricky considering the area of effect and the devastation it can cause, but rotation should be able to at least protect the user from being insta-killed with maybe some minor injuries to their person.
Raikiri - No, raikiri by itself is not capable of counteracting the rotating chakra the will eventually force the jutsu aside after sinking in maybe a few inches.
Sakura's CE Hyakugo Punch - No, this attack is not capable of breaking through rotation. Her arm will simply be forced aside, completely deflecting the blow, leaving the user unharmed.
Kirin - This attack is classified as a supermassive attack
Toad Blade Slash - If it is a simple slash, the user is more likely to survive as the blade will probably go most of the way through due to the mass and power, but the attack being too linear will keep the blade from harming the user.
