I don't have that recollection of the character at all. In fact, I would say Wuk Lamat's main flaw in the first half of the story is that she is an extremely passive character that you, the Scions, and Erenville (especially Erenville) to actually keep her on task. You need to lead around to accomplish anything, and her contributions are pretty minor (Thinking the festival is the important bit, and having a supporter during the trading questline).
Like Erenville's entire character for most of the first third of the story is 'Wuk Lamat wrangler.' She is portrayed as pretty seriously flawed early on and constantly goes to the WoL and has dialogue choices that amount to "I am unsure of how to do this" or "I lack confidence" and you basically get an (admittedly pretty basic) set of responses like 'Think about the people who depend on you' or whatever, or they do the thing where you silently talk and she goes 'oh that is good advice.'
If that didn't land for you, its fine, but I think its disingenuous to say 'There is literally no way you could interpret your character as having a mentorship relationship with this character' when the king *explicitly* asks you to have one. Like its not nothing, obviously, its literally not even subtext, its the literal text of the story.
I will say one other thing I do think is a legit problem with Wuk Lamat though, she gets way too much voiced screentime. I actually liked the voice actress, but even though most of the characters do contribute a lot all over the story, the fact that a lot of the moments where everyone is working together to solve a problem is unvoiced while the times where Wuk Lamat is having a moment are voiced does mean she is very 'over exposed' in this expansion.
