The new Odyssey campaign highlights a feature many people may have missed because they bring mastered jobs to Odyssey for segments: gaining JPs for NM kills. If you focus on that benefit, then it also makes it a good campaign to work on Moogle Mastery levels as well. This benefit would probably be even more well received if Moogle Mastery affected trusts in places outside of Odyssey. I'd obviously like it to work everywhere as a feature of the trust system, but it could also be a benefit that work in only some kinds of content.

Making this change would certainly give people motivation to do something different in their daily playtime than only segment farming in C. Incentivizing and diversifying content with campaigns is their best feature and I'd appreciate if they were further enhanced with tangible benefits that can help players at as many levels of the game as possible.
