I really do not like this duty, it is by far the worse duty in the game and actually made me angry.

Even though I do understand what they wanted to do with it I believe they failed to ask and answer a simple question: Is this fun? Because if they had asked that question they would understand that the answer is no. So even if it from a storytelling perspective should be included it should have been removed from a player enjoyment perspective.
Then again one could argue that other events before that point alrady make the point they are going for with this duty, which make this entire part of the story rather... well pointless.
