Yes because those are newly introduced characters and they can have whatever power ceiling they need for the narrative? And it has been established what commander level is roughly at. As for dragon we know nothing, only that he may be top tier( another power ceiling) as for zoro he is not a newly introduced character. We have been with him since the begining and it would make no sense for him to go from a perceived power ceiling to a new one without warning,its very very bad writting( almost fairy tail level). I want him to get there in an organic way like luffy did, and you should too. It would make you more attached to the character to actually see him climb up. But you do you.
Whoever trained you doesnt mean squat, luffy was trained by the pirate kings right hand and look how much he struggled. Garp is training cobby and helmeppo. Yet one is growing faster than the other. Whoever trains you doesnt mean as much as you think mate, just because you are trained by the wss for 2 years doesnt mean you are anywhere near his level after that. It just means you got a good teacher and thus may learn more. That argument is completely pointless.
I wasnt talking about CoC, i was talking about King( the character)'s haki and strenght. Akainu came back 10 minutes later completely fine, the only reason he couldnt keep fighting WB is because of the quake which removed his footing and made him fall down while WB got a hole blown through his head. Im saying that it doesnt matter if you think its fake hype or not, they happened and its a fact. Roger and WB fought for 3 days, yes or no?
