I've found literature to be a lot easier too, and I don't think reducing the dust reward last patch was a good decision. If anything, that change makes it even more grindy since you need to do it 3x - 4x more for the same reward earlygame, and by the time it's at 100% efficiency you probably won't really need it.
Edit: The rework made it better, though I suck at math even more lol
