I'm afraid it's not entirely working as some feel it's intended for. Roulette does not stick you where you're needed. I have been thrown into the Aetherochemical Research Facility 6 times in a row and none of them were first timers. There are five level 60 dungeons. Hitting the same dungeon 6 times in a row starts to feel less like a roulette and more like punishment.

Also, for people who "don't understand" why Aetherochemical Research Facility is so hated - it's simple: There's no loot. I don't mind being stuck there if at least one person there needs the clear, but with the addition of no loot it's even less appealing if everyone is a veteran to the place.
