no, no, no...you are not getting my point...why he let g2 or g3 remain weak?....with newly learnt haki, based on theory, it could make g2 and g3 far stronger....why he didn't even think about trying to solve timelimit problem? didn't he know he is consuming too much haki? why he didn't find a way to conserve his haki? at this point, he is not inexperienced rookie, he is someone with fighting experience and that cool down time happened not once but many times...this could have been the perfect time to work on that and yet the same old timelimit and someone has to save his ass again...
and for information, Kaido didn't let him hit, Kaido swung the club, Luffy dodged and hit Kaido in return...and even now Kaido hasn't bothered to defend himself, he is only attacking....
oh, btb I am talking about Luffy fight with Katakuri after merienda...he fought Katakuri for hrs with g2/g3 without losing haki and yet as soon as he goes g4, he loses in haki like after 20 minutes...
