They're not going to kill her off, and doing so because 7.0 had some writing issues would be idiotic. Don't worry, once we leave Tural behind Wuk Lamat will likely be relegated to small intermittent cameos like other leaders and not a major focus. Come 8.0 you won't be seeing much of her. But they're not going to rewrite the expansion or suddenly kill off its main character in some desperate attempt to over correct.
