How's Zoro meant to fight as long with 30 broken bones
He had his broken bones from trying to endure Kaidou's sum of approx 2 attacks tho. If Zoro cant endure 2 Kaidou attacks (Kaidou+BM 1 attack = approx Kaidou's 2 attacks) without broken bones, then Yamato who can endure so many more of Kaidou's attacks in tens of minutes timespan is clearly stronger. Just sharing how i think about it.
