I was a hot take enjoyer that actually for the most part liked Wuk Lamat and would say so after doing dungeons/raids as a sort of fun little incendiary device thrown into the chatbox while waiting to roll on loot.
Some 
hated her because she brought "cookie cutter sunshine and rainbows" (their words) to the setting, which is totally a thing utterly dominating fiction because there wasn't already a decade-plus of 
in fantasy fiction in overreaction to scary phantasms of "cookie cutter sunshine and rainbows."
Others hated her because feeemale... though as soon as word got out that the English localization voice actress was trans, things got wild very quickly. 
Outside of chuddery, there was room for criticism, especially for some not-great delivery during some key moments that could have used a re-recording with a little more passion to them, and yes the story pacing was slow (which I was fine with personally because my character was "on vacation" and wanted to take it slow and meet new people and learn the local cultures) which was a bit of a whiplash from the prior expansions. The old support characters in the Scions were under-used in favor of new characters, and that obviously is grounds for disappointment for some too.
