It would be nice if the developers changed the tribute from the various Kingdoms to include some random chance of the traitstones each Kingdom “specializes” in (in the Explore area) showing up.
EDIT: Because of the recurring motif in the responses, I’ll add that I’m asking for this simply because of game design reasons. Since each Kingdom specializes in certain traitstones, and they’re sending tribute my way for one reason or another, it would be more aesthetically pleasing and logical if that tribute included a bit of what they specialize in every now and again. Yes, I know. Don’t laugh.
