How many people advocating for these to not be changed regularly run them? I queued daily for Coils in Duty Finder and made PFs for weeks before giving up and unsyncing the fights to see the story.
There's no point keeping them around to not "dumb down" the game if no one plays them anymore. I'd rather see them get reworked to be more modern and able to be run more frequently than stay dead content nobody touches.
