Personally I'd have preferred if all 4-man dungeons and trials required for MSQ, leveling or not, were combined into MSQ roulette. Combine all non-MSQ required dungeons into a single roulette called Optional Dungeon roulette (that gives exp and tomes equal to the current leveling roulette). Keep Expert roulette. When the level cap increases, all previous expansion expert roulette dungeons are tossed into their rightful areas.
