I recently complained about this. I'm new the FF14 and hadn't run any of these dungeons. I wanted to unlock the roulette because it was content I hadn't seen and I wasn't keen on running the same two dungeons over and over again for a small gain.

Now I have ran the fifteen high level roulette dungeons and actually enjoyed it. I assumed to begin with that the hard mode versions of these dungeons were like heroics from wow. I was pleasantly surprised when I found out that they were a 'here what happened while you were gone" and some have great lore and fun bosses.

However. I still don't like how I was bottle necked into running all of these to unlock a feature that will typically reward less law. It is actually giving players less incentive play old content and even some of the older players in my FC haven't unlocked their HL roulette.
