Unless bro is just entirely weaker than the sukuna raid squad, it still matters.
I dunno if he was ever weaker than the people in the Sukuna raid squad. Tho he did have to try harder at some points throughout it. But these are also the same characters who trained their resilience to be on Ryu's level, so I don't see much issue with that.
You can send the panels of Gojo who is tanking Domain Amped Sukuna slashes even while not using RCT instead if you want. Honestly it looks like the only time bro lost a limb the entire fight was against WCS.
You talking about when Sukuna attacked Gojo while he had Simple Domain up which caused it to break? Cuz that's the only slashes I recall him throwing. The other ones were from the Domain itself which did admittedly didn't bisect Gojo, albeit the first slash in the domain would've literally took Gojo's head off had he not used RCT. Which is also excluding the fact that Gojo is > Sukuna physically (Which obviously includes dura), and it was also confirmed every slash on Gojo wasn't shallow until he started using Falling Blossom Emotion, in which is was noted the slashes were becoming shallow as a result of him using it. Implying every slash prior was causing deep wounds that would've killed Gojo.
Anyways, after looking, Gojo didn't get a limb cut off, tho he did evade every one of Mahoraga's cuts (prior to the WCS) to avoid being cut in half by his blade (The one that got closest to hitting him split his chest open). But for whatever reason if you still think cutting attacks don't mitigate durability he's some feats of cutting doing so.
Mahoraga tanking Sukuna's punches and then cutting clean through him with Dismantle immediately after
Mahoraga tanking a kick from Sukuna, and then having a dismantle once again cut through both him and the building they're in
Yuji states Yuta can turn him into mincemeat with his blade despite him believing them to be physically comparable at this point in their fight
Yuta casually stabbing Yuji in the heart with a broken blade while being held still with a casual push (Despite Yuji being able to send Yuta flying with punches, and them fighting on par throughout this battle, and Yuji verbatim steeling himself with CE)
Naoya punching a hole into Naoya with a small dagger/knife despite Choso being able to eat his normal attacks
Yuta cutting off Kurourushi's arm with a Katana despite Kurourushi being able to easily block Yuta's physical strikes
Like what else could you possibly want? Do you think sharp weapons in JJK have the same exact affect as ordinary punches and that cutting attacks in JJK are hot ass and nonexistent or smth? I don't see why Sukuna being able to cut clean through someone
weaker than himself is a problem when he can nearly take Gojo's head off in his Domain Expansion had he not used RCT despite Gojo being > Sukuna physically.
