It is not their fault...Oda does things that way...Onigaishima pre rooftop is a huge example and so far in this arc, Luffy didn't give any vibes of person who has 3 billion bounty...
We speak her about current Luffy, the one in end of wano was toe 1on1 with Kaido for a while even in Base/Gear2/Gear3 and this Luffy should be even stronger. Same for the Zoro and the other strawhats.
Oda now brining up Sentomaru is for me a signs that perhaps Kizaru or a other Admiral will show up in this arc.
Lucci and co get washed and ask for help, saying Luffy and co trying to take Vegapunk.
