“Post Arc is gonna go crazy!” they said.
The portrayal of Marines and admirals got wrecked by Sabo and Shanks.
Bullshit.
Revolutionaries
retreated upon completion of their mission and Shanks gave warning to a conflict Aramaki had no interest in
at the time - likely because he had no backup whatsoever, not that it would matter in a 1v1 because Yonkou >>> Admirals has always been obvious to anyone with a functioning brain.
Dragon is literally being overshadowed by Sabo before entering the damn story.
Dragon dwells in the shadows by choice. His entire character is a mystery and that's likely how it'll remain for some time.
Sabo on the other hand is a young, bright, charismatic individual with good looks, a flashy Devil Fruit and sense of chivalry. Naturally he would be popular.
They're each serving entirely different roles and in different lanes. Do you seriously think Dragon
cares Sabo is in the limelight? Laughable. If anything, he's pleased with the support it's generating for their cause.
Mihawk is now an ally (best case) or subordinate (worst case) of Buggy, and is both mentioned and regarded in the same breath as CROCODILE.
We have no fucking clue what their arrangement with Buggy is, yet people are already crying about it.
Crocodile isn't on Mihawk's level, but he is far stronger than you might think. Power-scaling in One Piece is fucked, which is why I make fun of dorks that obsess over it. In a span of mere weeks, Luffy went from struggling to beat Doflamingo to beating Kaidou. If that doesn't put things in perspective, nothing will.
As for Mihawk - the guy leisurely goes about his business in a coffin-shaped ship. What could be more in character for him than to join Buggy's crew under conditions he finds suitable? No one can claim master over Mihawk, the guy can
pretty much do
whatever the fuck he wants,
wherever he wants, and to
whomever he wants.
On his own. I could see Mihawk joining on Buggy on a whim or for multitude of other reasons; whether it was to amuse himself, converging interests, or maybe he's merely sticking around because they've got good booze.
Oda doesn’t give a shit about legacy characters.
For one thing, that more often tends to be a good thing than a bad thing.
Secondly, you're completely wrong on this considering the number of characters introduced in early One Piece that are still around. Buggy is the biggest legacy character of them all - he was such a minor villain at the start and Oda developed him into a pretty integral character (miss me with that bullshit Oda had it
all planned out), and I'm not just talking about his becoming a Yonkou. Impel Down was a phenomenal outing for Buggy as a character.
Crocodile went 100s of chapters without an appearance before becoming a significant player during Impel Down and Marineford, and he's still around.
Arlong, a freaking nobody, had relevance during Water 7 and Fish-Man Island arc.
Coby had the biggest glow up of them all and he appeared in chapter one.
There are dozens of characters that Oda introduced earlier into the story that remain relevant and impactful down the line, and he's doing it without forcing it.
