VFDC's example of a wiki page is something that is very comprehensive and the related on articles on each character is what people should strive for achieving.

The FSD wiki is behind even the dustloop wiki examples that some characters haven't been even filled yet and some are empty (ie: Mila, Momiji, Raidou and others).
I'd suggest shortening sections with backstory information or removing fluff, while instead of having a singular section for gameplay, there are seperate articles for character strategies, move analysis and starters. The DOA Wiki already does a good job of doing fluff and story articles, so there's no need to redo the same formula.
DOA Wiki's costume articles are good for linking. No point in dumping costume images in wiki pages.
The
blue violet wiki has already done 99% of the frame data for the game, so I suggest that should be used as the primary frame data source.
I can write a thesis about characters I know on my own, but I don't know about most people here. If multiple people can get together and keep editing and adding to one article every once in a while, there can be a lot done in a short amount of time.
