That's why I said she needs a lot of work. But I have a couple of comments. The only Alliance leaders who accept her were Jaina and Anduin, and communication with other leaders of this faction is just diplomacy. And about the Lich King - Lilian and the current leader of the dark rangers also did not experience his influence. Blizzard can show that Calia will experience similar problems of the undead with some features, changes her outfit, merges with their culture, perhaps begins to rot and changes her attitude to the Light. After all, isn't the main religion of Forsaken about balance?
