Wow did this, it lasted like an expansion and a half before they got rid of it.

Problem was it wasn't at all indicative of how an actual dungeon would go and depending on your class much, much harder than simply ..running a dungeon. And you had to do this to be able to enter heroic dungeons. It was a failed experiment. I'm a good, experienced player and it was a major PITA on some of my classes. It wasn't fun, it didn't teach me anything, and I don't know anyone who liked it or thought it was at all useful beyond basically being a gatekeeping function.

So yeah, we don't really need this in FF14, please and thank you.
