in SL from your mission table you get a purple adventure campaign progress?
are those for better anima gain?
Essentially, it’s just a chain of missions (“campaign”) that progressively get harder. They give better rewards, and increase the level of your missions as you clear them. Not overly worth it if you’re going only for anima (though progress does offer more per mission through scaled difficulty + rewards, but it’s not significant, ZM is still the best place to farm for Anima). It does has benefits for completionists though (ie mount reward, companion xp books, etc).
You can read more info about it in the WoWHead comments.
