Ace being freed is 5 times more impactful than anything in wano even comes close to. Whitebeards fruit reveal is 10x more interesting. Aces death is 30x more emotional than anything that's happened in wano. Whitebeard vs kizaru was way more interesting than Whitebeard vs Roger.
Ace's death is the most emotional thing in the
entire manga though, and it's ripples were still felt strongly in this arc with both Tama and Yamato.
Outside of tragedies that effect Luffy or Strawhats directly, it is hard to feel empathy for fodder characters created in 1 chapter to be exploited emotionally the next chapter.
Do I care that Killer was tortured and forcefed a SMILE, not really
Do I care that Wano citizens killed their children to save them from starvation, a little bit
Do I care that Yasuie was executed, not really
Do I care that Oden was boiled alive, a little bit.
All of them are tragedies, none of them directly effect Luffy or his crew.
Do I care that Tama would have been waiting like a dog who lost his master, until she died of starvation, for Ace who died without her knowing due to Wano's closed border, yeah I do.
Do I care that Ace and Yamato shared a promise likewise, and that she was stuck trapped by her father until Luffy came to save her, yes I do.
Do I care that Luffy's courage drove Momo to the conviction to sacrifice 20 years of his youth to save his country? yeah I do
Expecting Luffy to take major deaths like that in front of his face spit in the face of his 2 years training which was specifically to avoid that.
