Oh, if we're going to kill her, people will be saying that the raid where we kill Sylvanas and another batch of prominent Horde figures is yet another example Horde bias. After all people used and still use SoO as an example of Horde bias, lol.
If we, however, don't kill her in BfA or ever, people will be saying that it's Horde bias because Blizz will once again let evul Horde character live.
