I agree with you. It wasn’t just Wuk Lamat that was the problem but also the place of our character in the story.

I didn‘t even think about those points of yours but for all the flaws Zenos had or Ardbert as a plot device they were good counterparts to integrate the WoL into the setting.

Either they learn how to use our power better in the story and write around it or the WoL needs some kind of check, like a seal for example.
Maybe even use politics because that’s still our weakness. They had the stuff with body swapping.
Why not „clone“ the WoL with a soul from someone we already forgot or that is dead? Like Illbert.
Or use it on one of the Emet Selch clones.

That one could do heinous stuff and we could lose support in some form and even try to reforge our reputation.

Not saying these are good ideas, they are probably even more stupid.
But it would be better then being nonexistent.
