When will they update lvl 60 dungeon roullette?

[Colorful]

Thats what I am talking about? Are there more dungeons at lvl 60? (not counting void ark and alexander savage)

Yeah, there's 5 so far:

The Aetherochemical Research Facility
Neverreap
The Fractal Continuum
Saint Mocianne's Arboretum
Pharos Sirius (Hard)

But only two for the expert roulette. I find myself capping really quickly now though, the occasional Diadem run, Void Ark farming, DREX 3-4 times a week, Level 60 roulette and Alexander if you're gearing alts. There are plenty of options.
