Item: One Piece

Language: en

Type of Problem: Incorrect_content

Extra Details: Preamble: Sorry for the amount but it's kind of a mess :P Needed that myself to get this sorted.

While naming the Seasons of One Piece I noticed that the episode ordering or rather season-affiliation is totally weird in this... This is more of a general issue and I reported some episodes already, but that was before I realised that there were way more problems then I saw at first.

I don't know if you aim to have the same sorting that TheTVDB does, or want to have a custom sorting, but currently it doesn't seem to have either. As a result the Season Posters and Episode images don't really match up with TheTVDB data if that is desired.

Now as you're probably well aware long-running anime like One Piece don't have traditional Seasons. In TheTVDB they mostly divided them by the official Arcs and/or Sagas (see the Episode Guide in the wiki). Now I just realised that TVDB has some issues there too but since editing anything there is a pain in the rear I'd rather contribute here, but that's another issue.

To the point, the current state is as follows:
[OK] Season 1 - East Blue Saga: Episodes 1-61 (including Filler Arc); TVDB Season 1 to 4
Note: I actually like it the way it's handled here. The East Blue Saga consists of a few shorter stories and is basically the assembly of the first crew. Making each Arc separate like TVDB does it is a little overkill, tho not completely wrong.
[OK] Season 2 - Part of the Alabasta Saga, Episodes 62-77: Reverse Mountain, Whiskey Peak, Coby & Helmeppo, Little Garden; TVDB Season 5 to 6e8
[OK] Season 3 - Part of Alabasta Saga, Episodes 78-91: Drum Island Arc; TVDB Season 6e8 to end
[OK] Season 4 - Part and Conclusion of Alabasta Saga, Episodes 92-130: Alabasta Arc; TVDB Season 7
[OK] Season 5 - Part of Alabasta Saga and Sky Island Saga, Episodes 131-143: all Filler so it doesn't matter; TVDB Season 8
[OK] Season 6 - Sky Island Saga, Episodes 144-195: Jaya and Skypiea Arc; TVDB Season 9
[OK] Season 7 - Sky Island Saga and Water 7 Saga, Episodes 196-228: G-8 Arc (Filler), Long Ring Long Island (technically Story but feels like Filler), Ocean's Dream Arc (Filler), Foxy's Return Arc (2 Episodes Filler, 2 Story); TVDB Season 10 and Season 11 E1+2
Note: Personally I'd move the G-8 Filler Arc (196-206) into the previous season (see below), it blends directly into the Skypiea story arc (coming down from Sky Island). Also Episodes 227 and 228 should be moved into the next season. I don't know why they are listed in a Filler Arc on the official lists, but they are not Filler episodes and an introduction to the next Saga
[OK-ish] Season 8 - Water 7 Saga, Episodes 229-263: Water 7 Arc; TVDB Season 11e3 to 11e37
Note: Splitting this into its own Season is OK-ish, since Water 7 storywise works towards Enies Lobby, but it has this point-of-no-return-kind-of-thing where they can't go back to Water 7, so w/e
[OK] Season 9 - Water 7 Saga and Thriller Bark Saga, Episodes 264-336: Enies Lobby Arc, Post-Enies Lobby Arc (Saga Conclusion), Lovely Land Arc (Filler); TVDB Season 11e38 to end, up to Season 12e11 (Lovely Land Arc)
[OK] Season 10 - Thriller Bark Saga, Episodes 337-381: Thriller Bark Arc only (yay!); TVDB Season 12e12 to end
[OK] Season 11 - Thriller Bark Saga and Summit War Saga, Episodes 382-407: Spa Island Arc (Filler), Sabaody Archipelago Arc; TVDB Season 13 up to e26
Note: Spa Island Arc (382-384) should be moved into previous season (see below), it's also listed in the Thriller Bark Saga on the wiki
[OK] Season 12 - Summit War Saga, Episodes 408-421: Amazon Lily Arc; TVDB Season 13e27 to 13e40
Note: This could be combined with the Sabaody Archipelago Arc since both are rather short (in One Piece terms anyway), and Sabaody also kicks off the whole crew-is-separated thing in the Amazon Lily Arc

Up until this point everything is kinda OK (I guess)...
[OK] Season 13 - Summit War Saga and Fishman Island Saga, Episodes 422-522: Impel Down Arc, Little East Blue Arc (Filler), Impel Down Arc (continued), Marineford Arc, Post-War Arc, Return to Sabaody Arc; TVDB Season 13e41 to 15e6;
Note: Between 516 and 517 there is a 2-year timeskip. It would make a LOT of sense to move 517-522 into the next Season/Arc, it belongs to the following Saga anyway and doesn't conclude the previous events or anything, the episode title even says it "A New Chapter Opens". I would even go further and make a split between Impel Down Arc (up to 456) and Marineford Arc (457 and following), since they have distinct separation, Impel Down is basically all of the preparation that goes into the Marineford Arc, which concludes the whole Saga. Now granted this is a matter of taste but I feel like it would be the best way.
[OK-ish] Season 14 - Fishman Island Saga and Dressrosa Saga, Episodes 523-580: Fishman Island Arc, Z's Ambition Arc (Filler), Punk Hazard Arc (2 episodes); TVDB Season 15e7 to end, Season 16e1 and 2
Note: Really just move the last 2 episodes to the next Season, they belong there.
[OK-ish] Season 15 - Dressrosa Saga and Yonko Saga, Episodes 581-642: Punk Hazard Arc, Ceasar Retrieval Arc (Filler), Dressrosa Arc (partly); TVDB Season 16e3 to 17e14
Note: As mentioned above, 579 and 580 into this. Further, move 629 and above into the next Season. They are completely out of place here. I think when they were created it wasn't expected that the Dressrosa Arc would be that long, but oh well... that happened (2 goddamn years)
[No.] Season 16 - Dressrosa Saga, Episodes 643-692: Dressrosa Arc (partly); TVDB Season 17e15 to 17e64
Note: Not sure what happened here, but for some reason it just stops in the middle of the arc (ends at 746). Also as mentioned before, missing some Episodes from the previous Season
[No.] Season 17 - Dressrosa Saga and Yonko Saga, Episodes 693-748: Dressrosa Arc (partly), Silver Mine Arc (partly); TVDB Season 17e65 to 18e02
Note: As mentioned before, this whole season should be combined with the previous season together with Episode 749 and 750 (since they are Filler)
[OK-ish] Season 18 - Yonko Saga, Episodes 749-767 (still ongoing): Silver Mine Arc (Filler), Zou Arc; TVDB Season 18e03 to 18e21 (continuing)
Note: See above, first 2 episodes into the previous Season and let this be on its own

A general note regarding Fillers: Personally I would always move them toward the end of a season. Starting a new season off with a filler is kinda meh, and since they usually don't integrate into the story anyway. Luckily not a whole lot of them are actually at the start of a season here, I noted them above.

In addition to all of the above, what's wrong with the episode counter? It's split into seasons but the episodenumbers correlate to the absolute numbering. I've also seen this on Bleach and Naruto/Naruto Shippuuden. Is it supposed to be this way? Is this a special rule for long-running series until we get "real" absolute nunbering?

I'd love to do this myself but since there seems to be no way of moving/deleting episodes (just adding) I can't (though I can see why deleting and moving wouldn't be possible). Discussion also welcome :)
