+1 for moving CT to MSQ roulette. If only because I think it would make AR roulette more fun. I think two of the three duties in MSQ roulette are also 17 minutes, so this should be fine?

I also think the The Aetherochemical Research Facility should be moved from High Level to MSQ as well. So many reasons: no chests, 4 bosses, "17 minutes", and "big MSQ moment in the cutscene". It's practically the Praetorium.
