LMFAO! Lets go this one by one.
"That Joyboy is the one who left One Piece where it is, it was not Roger's treasure" this is head canon. All we know was that Joy Boy was there and they laughed. Also, we knew about Joy Boy since Fishman Island and Marine ford when White beard said Roger isn't waiting for you Teach. The only info we were given in wano was that it was funny Big reveal there and Roger were too early.
"- Was responsible for the Ancient Weapons" head canon
-"- Left an extraordinary tale that causes the entire crew to laugh in a very cryptic way." lmfao! Big reveal there that people are laughing.
"- Learned that Roger was too early to do anything" already discussed above.
"- Had Oden to decipher the Poneglyphs and leave a message on skypiea." we already knew they couldn't read the ponelygyph since Sabody arc! That isn't new information!
"- Introduced the concept of Joyboy and his return to the mermaid princess." this was all the way back since fishman island! That was 11 years ago!
- "- Rocks, God Valley, etc" that is another filler content ODa created out his ass.
Ah yes, let's cherry pick 5-6 points out of the 15 I gave you and act like you are winning the argument.
You compared pre-timeskip to post, doesn't matter if shit happened 11 years ago. Doesn't matter if new lore is created that works.
Rocks is filler? It is literally the driving backstory behind Kaido and Big Mom's alliance. We did not know about Oden pre timeskip.
You are a weird and funny person. You complain that Oda doesn't give you new information/lore about One Piece's biggest secrets (which is mind-bogglingly false), then also have the audacity to say he "creates filler" that he "pulls out of his ass"
You are unironically the biggest hypocrite on this forum. Enjoy the chapter, we all know you secretly do, cause you come back for more
