Remove ARF from the MSQ

[MilesSaintboroguh]

I was surprised when I first unlocked Expert Roulette and found out that this dungeon wasn't part of it. Its longest cutscene occurs after the boss has died, so the most waiting you'd have to do is probably 1 minute before the final boss fight. Its boss fights are also arguably funner than the opening burst rotation-interrupting trolls from Neverreap, and a third dungeon in the mix would have helped lessen the monotony of Expert Roulette.

Expert dungeons generally have the same ilvl requirements. ARF has a lower check (and if it had rewards, less valuable loot), thus it would be considered "too easy" for an expert label.
