Never said it was. I think you're misunderstanding and overcomplicating what I'm trying to say. It's more that, a different writer, with better ideas for him and a more well-thought development, was able to make him a more interesting character. I don't think he was meant to be as unlikable as he was during base-ARR, but that's another discussion.
And no, I do not think a character has to be a "goodie two shoes fluffy anime cheese cake" to be likable. Please don't assume things I never said.
My overall argument is just that the character isn't the problem, and getting rid of them won't solve the main issue. If you don't change the writing, even if you get rid of the character, the problem won't be solved. Even in different iterations of the same character, there still must be elements that make us identify them as THEM, thus separating them from the writer. And I honestly think that those traits that make Wuk Lamat identifiable as herself could be well used by a good writer. That's it. That means THE CHARACTER isn't the problem, but how she was written.
See, you just agreed with me. If you just said "the iteration of the character suck", you just separated the character from the writing, like I'm trying to tell you. You identify that character as a separate entity that was treated differently by another writer.
Do you agree that Wuk Lamat could not suck as a character if the writer were competent? It wouldn't be about changing her personality, but making her actions coherent with her motivations, giving her well developed growth and appropriate space in the narrative.
That's how you separate character from writing.
That's what I'm trying to tell you from the beginning.
My point is, getting rid of Wuk Lamat will make us breathe a little from finally being away from her after DT, but if the writers don't change, nothing will be solved long term.
Really I was just answering your "And ... how do you differentiate between the two?" over there.
