Right now, Aetherochemical Research Facility is one of the least-queued-for instances in the game. Only level 60 players can access it, but they are far more likely to use their leveling roulette for an alternate class or job (six Esoterics is not worth doing it at cap, at least in my opinion). Even if they were to use their leveling roulette for Esoterics, there is a very small chance that they woulds wind up in Aetherochemical Research Facility (for me, it's about a 1/20 chance, or about 5%, assuming even weighting).
This has led some others in my Free Company to have extremely long queue times for the dungeon, which is required at 60 before finishing the story and unlocking endgame content.
Given that it is required, and given its relative difficulty when compared to the other leveling dungeons, I'd like to see Aetherochemical Research Facility included in Duty Roulette: Expert. It would get a lot more people doing the dungeon, shorten queue times, and add a bit of variety to the daily Expert queue. Esoterics would need to be added after the first completion to make it worth it, but adding it to the queue with an iLvl sync (to ~170, to be nice to fresh 60s) would be a very nice addition.
