Allow Level 50 Roulette to unlock progressively (as other Roulettes do)

Edit: A reply clarified that other Roulettes share the non-progressive lockout system of Level 50 Roulette. (but I can't edit the post title)
My opinion on the matter, and QOL suggestion regarding it, extends to any Roulette with this Pokémon unlock system. I think it is both counter-intuitive and unnecessary, there are better ways to incentivize players to unlock unpopular dungeons.

I'm currently working on my ARR Relic, and I just received a useful quest — Morbid Motivation — that asks me to do Level 50 Roulette.

However, Level 50 Roulette is locked behind a list of dungeons, such as "???", and another which sounds even more exciting — "???".

I know (from outside research) that these must be Snowcloak and Keeper of the Lake. They're not unlocked because I haven't reached that point in the MSQ yet — and I refuse to rush the storyline just to unlock a roulette.

I believe the developers' logic for structuring L50 Roulette this way is to ensure that players don't just unlock a handful of easy dungeons, ignore the others, and thus defeat the point of the Roulette (helping players complete orphaned or outdated content).

I think that L50 Roulette should work like every other Roulette: upon unlocking at least two L50 Dungeons, the L50 Roulette should become available.

A simple incentive — such as a Title, Achievement, Minion, repainted Mount, or something — could then be provided to encourage players to still track down and unlock all Level 50 dungeons (to keep the Roulette pool diversified).
