Restructure 50/60/70/80 Roulette before Dawntrail

Having 50/60/70/80 roulette was already more than a mouthful. But it's also kind of un-fun because of the extremely high likelihood that it's going to be from a handful of specific story dungeons, and we very seldom see some of the fun optional side dungeons such as The Twinning or Smileton or Sastasha Hard Mode, etc.

Here's my list of suggested solutions:
Move The Aetherochemical Research Facility to Main Scenario Roulette

This duty, with all cutscenes watched, takes approximately as long as The Praetorium. It belongs in MSQ roulette, not with the 60 dungeons
Introduce "Epilogue Roulette" comprised of the remaining x.0 and x.5 MSQ dungeons

The Keeper of the Lake
Baelsar's Wall
Ala Mhigo
The Ghimlyt Dark
Amaurot
Paglth'an
The Dead Ends
The Lunar Subterrane
Rename 50/60/70/80 BEFORE it becomes 50/60/70/80/90

"Tales of the Star Roulette." It was already hard enough finding a way to refer to this LOL, a name to it would be better than no agreed-upon abbreviation. All remaining former Expert Roulette 4-player dungeons would go in this roulette.
Hope this would be useful! To be honest I don't think it would overload the tomestone economy much more than it already is as there is so much variable content these days beyond roulettes. It would just shake the roulettes up, giving newer players a chance to have better than doing an optional dungeon one time and then never ever seeing it again.
