From a lore standpoint, it's not at all unthinkable that Wuk Lamat may have a northern Latin American accent rather than a southern one. Though Tuliyollal is geographically where South America is in our world, in universe, it is much more culturally diverse due to its ruler uniting many of the disparate peoples of Tural. I would assume this includes people from Xak(North) Tural as well.
While there may have been a few instances of stiff delivery of lines in this patch, I think the VA did a good job of getting me invested into the character of Wuk Lamat and I look forward to hearing more from her in Dawntrail.
