While I try and be positive about the narrative, I think this was another wasted opportunity. At least put in a bit of a breadcrumb trail, or require us to do some thinking, not just "oh, read this, it answers the questions of the last 2 years plotline in 1 paragraph".
Rather reminds me of the "rescue the Emperor" non-event. Oh look, it's happened in the background, not even an attempt at player engagement.
sigh
And what's frustrating is that it wouldn't take much effort, or thought, to make it so much better.
