She did make sense to me before, but now she doesn't really. So for me the question should be opposite: Why doesn't Sylvanas make sense for you anymore?
She lost her cool. That's why. She be cunning, clever and lurking in the background. Now she be all over the place, strong af, and I have this feeling that she will be the redeemer so she will be even more unlike herself. That's all my opinion. I don't like her in front of all I guess. Saying that, she is still cool. But not the same. But, still cool, oh yeah.
Yup. I guess that's always going to be a fault with a game like this when the story is told for 2 hours every 6-8 months, but I sure hope we get something between 9.0 and Shadowlands release that will tell us something. Like War of Thorns.
But a clue would be nice between all these years. Though I doubt this was in Blizzard's plans since the start so it's probably a fresh idea(like 2-4 years)
