I get where you're going with this, but I still find that Calia as a whole is just a downside to the entire process. If Sylvanas was aloof from the Forsaken because she had a public face and a private contempt, then Calia is just entirely removed from the Forsaken experience. She's condescending without even meaning to be and even when the writing doesn't seem to intend it, like greeting Voss and praising the father who raised her to be an instrument of war and then nearly killed her. Everything is easy to her. I can buy that some Forsaken would be drawn to this perfection and escapism, and in that regard you can have a story with Calia, but the fact that Voss purposefully seeks her out instead of taking up a guiding role herself and that the lesson the Forsaken take is that blindly following a leader is wrong so they better blindly follow a different leader, this time one that doesn't do shit is just anathema - not just to what the Forsaken ahve been for fifteen years, that goes without saying, but beyond that it goes against what they were meant to learn in their BFA incarnation.
Voss herself is a far better representative of this bridge or, if we really must, Derek, simply because they have a frame of reference that Calia doesn't. Calia is an idealized figure, an idol more than a person. On the other side to Voss wishing to reconnect with humanity and gripped with regret, you could have Belmont or better yet, Lydon what with him being the designated successor before, possibly with a council of three going, who's reaction is less "What do we do now without Sylvanas" but "How do we make Sylvanas pay and not have this moment of weakness be exploited". The Calia story as it is is simply too easy, too far removed from any incarnation of the Forsaken and just altogether condescending. If I didn't know better, I'd say @
ChairmanKaga was right and it was deliberately made to annoy, akin to the previous "Light fixes everything" copout with Illidan where that ended up being the intended audience reaction.
