After completing the Living World, main story, and expansion stories, is there any reason to do them on another character? You don't get any additional mastery points. I guess the main reason I do starting episodes is to give another character access to the HoT, PoF, and LW maps. Are there other reasons (besides that the story is really fun for some people)?
I don't mean to troll. I'm happy doing world map completion on many characters. I just don't find the LW and expansion stories all that fun a second time around.
