Well, roulettes also give you up to date content, some of it is difficult to some people, and leaving is still rare. Most instances of leaving apply to content that was considered notoriously difficult or tedious to do, such as Aurum Vale or Orbonne Monastery. And people still leave those even when we outgear them. Back when Heavensward and Stormblood content was relevant, I don't recall there being a leaving problem either, and people who used to play back then are more experienced now. More fun also doesn't just mean slower, but generally involving more effort than old content does now. My post wasn't aimed for a one time (or every once in a while) re-experience of older content as it used to be, but more to let daily roulettes be less boring and monotonous to do.
