I love everything about Wuk Lamat already, that clearly both her heart and skills are in it even if she's a completely inexperienced wimp in reality. It's entirely possible we could see a Lyse-style angle unfold, where she realizes that her style of leadership doesn't actually sync up with what she thought the country needed. Although something else I could see them doing is us learning that she actually is good at the important parts of ruling a nation, she's just woefully underequipped for the actual rite of succession, that demands a completely different skillset. Which is honestly an element of leader-selection in general that I wish more media explored: that 'ability to undertake the leadership role you're going for' usually has nothing to do with the process in which we select a leader.
...but you're also completely right, that the big Discourse Subject of Dawntrail will absolutely be 'Wuk Lamat is a bad leader'. And I'm sure it's also going to be a complete coincidence that those people are always gonna put forward one of the male characters, including the one that explicitly wants to take them to war.
And all of those people are wrong, Wuk Lamat is great. I took a bit to completely warm to her voice acting, I did have that struggle of 'this is a new accent to me and I need to get used to its cadence', but even then I adored her character, and her, Krile and Erenville will make for interesting parts of the 'A-Crew'. Unfortunately, every other choice for the Scions is exceedingly lame; there's nothing new to say about the twins or G'raha as allies (and yes, I know G'raha is staying home, he's still an ally), while getting Urianger in a core party without getting pushed aside by sheer cast size is overdue.
Finally: as someone whose chocobo has been named Tritoch this whole time, I'm happy to see that Valigarmanda will get such a starring role.
Yeah, turning up the volume on the Hippo Riders' Initial D to the point where it turns into Speed Racer (or possibly Wacky Races, the line is kinda blurred) is fantastic, and honestly, any further exploration of the Nibirun is welcome: I find it really interesting to see the exploration of exactly how their 'world without suffering' had nothing to live for: being so focused on avoiding the negatives of an experience that they also cut out the positives, with the concepts of adrenaline and competitiveness being completely foreign. It was quietly there in the Omicron quests, but it's nice to see it take center-stage, and it's empathetic in its way; I certainly know the experience of having staunchly avoided a badfeel so much that I forgot the joys that came before it.
