I'm not sure if anyone really brought this up previously, but I have a feeling that a lot of the repetitiveness (and the "tell don't show" dialogue that was employed in Dawntrail) might have been an honest attempt by SE to cater more to story skippers.
I feel like a lot of the heavy-handed goal stating by Wuk Lamat was to ensure that anyone, no matter how much story they skipped in the past or how long of a break they took between MSQ quests, would have a basic idea about what Wuk Lamat's goals were in a particular scenario and how she feels in the moment.
It is very easy to take a break in the DT MSQ and come back a month or even a year later and still understand what's going on, generally speaking. I also think that's one of the reasons why so many people compare DT's writing to that of a Saturday morning cartoon or something. It's simple and easy to understand, and a lot of plot points are simply stated outright instead of left to interpretation.
That being said, a lot of the complexity that some fans were expecting from the story was relegated to subtle hints and references.
I just wanted to point this out as just another way of understanding some of the decisions that SE made with Dawntrail.
