Back in Shadowbringers the content I enjoyed was mostly the extreme trials, and other more widespread content like Bozja, etc. I just wanted my dragons. I realized very early on that it wasn't going to happen with a job that was as laden with as many problems as Shb SMN. So I did them as Red Mage and Dancer instead.

The main thing retaining people now is almost certainly its thematic accuracy and spectacle, and despite the lack of buttons this may come as a surprise but there are people who like having a rotation with natural flow to it. It really is just that simple.
