I'm halfway through MSQ and I have mixed opinions so far (Currently finished Dungeon 3 in Dawntrail).
Was Wuk Lamat bad? No. Could she have been written better? Yes. Wuk Lamat is a good character, sheletered princess who develops and eventually leads a nation. I didn't like her much at first but she kind of grew on me to be a more likeable person. I just think she was written poorly. The story's execution didn't help either. The story's writing felt really weak at times. I did not feel as connected to the story as previous ones and there was a lack of emotional investment for me due to the lackluster writing. I did get what the writers were trying to convey. I just think it was done poorly. There's a lot of things that the writers get that we as the players don't know or are aware of, and I think that miscommunication really shows in the writing. Other times, it feels like they're repeating the same points over and over for no particular reason. We don't have the same insight because we are not the writers. Some reveals come out so leftfield that it's hard to relate. I think that is something the previous writers take extra care when writing.
The comedy and humor felt a bit forced at first and very unnatural, but it has slowly gotten better as I progressed through the MSQ. I sometimes get a weird impression from Wuk Lamat's voice actor feeling slightly monotone too and wasn't able to fully portray the emotions of some scenes. Maybe it's just the nerves, because the voice acting seems better later on.
The music isn't bad, in fact some of the soundtracks in various zones became my favorite song choice in this expansion. However, the musical execution to the some of the cutscenes felt very lacking this time around. Poor choice of music for the vibe, or the execution and the way the music cuts off for some cutscenes felt bad / left a bad taste in my mouth. Maybe it also has to do with the writing, I'm not sure. It's such a stark contrast compared to previous expansions that it became noticeable.
For example, I'll talk about 2 particular points that had a big contrast in its storytelling to me. (Trying to avoid spoilers) -> The Instance battle in The Xobr'it Cinderfield and the follow-up cutscene before going into the Ja Tiika Heartland. The cutscenes for the opposition felt just... very rushed. Very forced. I can sympathize with the plight of the characters later on, but there's not much context before going into the second half of the zone and going through half of the story for that zone. We got a claimant's one scene flashback before we went to Ja Tiika Heartland, and I think that random flashback has such a weird dissonance to us as the reader/viewer as there's no context to anything at all. Sure, we learn about it, but we don't even see the exact details until reaching near the end of the zone. There's no context until then. The storytelling felt a little lacking.
I understand a part of the reason why this is done is because they want to make Wuk Lamat learn the importance of the next zone. After all, a big part of the story is understanding. However, I felt like this could be handled better. Maybe if there were more signs done through the storytelling. All we saw was arrogance of the claimant, not the suffering underneath it. They felt very 2-Dimensional as a character only through a lack of means to see through the lens.
As for the build-up cutscene to the Instance Battle before the third dungeon, the second cast felt a bit weak in context since that group aren't necessarily with the main party (so we have only a general understanding of their personalities and motives). However, it was understandable what they do during the cutscene due to the build-up from the previous zone and the events in the earlier part of this zone. All those things combined led to a very hype/exciting moment. We understand their motives and choices because there is sufficient build up. Although the execution to this instance battle is flawless, I felt like the writers could have done a bit better to show the motives that drive this claimant's decision beforehand to make the point far more noticeable.
There are places I really enjoyed in Dawntrail. The graphical update helped in these instances make the place look vibrant and amazing.
As for the encounters and battle design, it's an improvement from Endwalker. Endwalker encounters were... bad to say the least. The fight encounters here feels much better in Dawntrail. Though only time will tell whether that will remain true later down the line.
Overall, I like the general concept of the story and where it is headed. I am looking forward to the rest of the MSQ. My opinion of some things may change as I continue to do MSQ.
