Okay-ish doesn't mean that it would be good. It could still be the worst expansion so far, but at least it would be better than what we got. Not having the most annoying and worst written (and with the worst VA, if you play in English) character on screen 99% of the time would definitely help in achieving that.
I don't know what makes you think that people are talking about the character as if it was a real person. Criticising her in particular doesn't mean that anyone sees her as a real person, and I don't even know what made you think that way. Maybe some people's jokes about her? Anyway, this has already been explained by other posters.
And you are not calling for anyone to stop talking, but you were saying that their criticism is "whining" and "having real life issues with the game". You're basically disregarding other people's opinions by making stuff up, instead of reading what they are actually saying.
Moreover, yes, she's the most inconsistent on this expansion. Not because of how she acts (she is who she is), but due to her several insane power increases out of the blue that make no sense just for the sake to keep making her the focus of the story (like being able to beat Bakool Ja Ja, or fight as equals with improved Zoraal Ja), up to the point of even forcing her into the last trial over Krile or G'raha, which were also there. The only other character that did anything similar was Zoraal Ja, and it was properly explained why (30 years plus alexandrian tech). And since you mentioned it, even Bakool Ja Ja's original attitude is explained, and he doesn't change all of a sudden and without thinking twice about it (hint: his mother, the only one that apparently gave him some love and didn't treat him like a tool, made him listen to find another path to end with the deaths of their children).
Lastly, nowhere did I say that if Wuk Lamat didn't exist Krile's story would be well written. I said that there would had been more time to properly develop that story, among others, which is one of the things that make the writing of the expansion this bad. I mentioned this even when I said "I'm not saying that that would had guaranteed that the story was good, but that not being there DID make the story worse." It's curious that you, being the one asking others to not criticise Wuk Lamat so much and instead focus on the writing as a whole, missed this. I think that you insist so much on your thought that people criticise the character, that you miss why we're talking about her. This is not just about her being badly written, but about the fact that she being so badly written (which is not limited to her a character, but also to how she's shoehorned everywhere) ended up affecting other parts of the story.
