As bethesda officialy ended support for Skyrim and no further dlc's will happen. I want to ask you this simple question:

What would you add to the plot/characters/enviroments that could potentially lift the questline up?

This thread is not for gameplay addons. So don't spam "Spears!" etc. etc. Only story content is viaalbe answer.

For example: "NPC X has no backstory", "This character was underdeveloped" , "They don't have a clear motive", "I didn't feel closure after the storyline x ended" and so on.

It would be nice if you could describe and provide links to similar stories in movies/games that in your oppinion took the same concept and done it better than this expansion.
