Can roulettes get an exp boost? Leveling roulette < 80+ dungeons

[Exosapien]

I feel like only leveling roulette is meant to give enough exp to warrant using it for leveling. If you get a dungeon at your job level in the roulette it's ideal, but generally outside of the daily bonus it's been more efficient to spam the highest level dungeon instead of queueing roulette multiple times. The "capstone" dungeons themselves don't give as much exp as a odd numbered leveling dungeons, and the exp reward for the roulette is... not much. I do wish that were better too.

Also it would be great that when doing a leveling roulette it considered your job level and gave you an appropriate dungeon, however I do understand there are at least a couple legitimate reasons why they don't.
