While FFXIV frequently references past games and few other Square-Enix IP, I'm thankful that with Endwalker all of the important encounters are all FFXIV-specific rather than just a fight thrown in for the fan service. The Magus Sisters and Anima still get their screen time as fights but beyond their relevance to the story that's all they get--and frankly, while I get the importance they each had in previous games, I'm glad that's all they got.
