That is itself the problem. Voss herself would be far better equipped to 'help' any of the Forsaken because she's actually been a part of them. Ditto someone like Cozwynn but I doubt Blizzard even remembers she exists. Voss has actually been through what they've been through up to a point - she was never part of the personality cult, mind, and she's a lot more powerful than your average Forsaken but she experienced crisis and loss, she didn't want to be resurrected and she suffered rejection by the living and by a figure she loved a lot who now said she was less than nothing (her father). She can relate to the Forsaken. But instead of it being her reluctantly coming into her own as a guide to the Forsaken or putting together a council, we're told that the one who really understands and can bring hope to the Forsaken is someone with no frame of reference of their condition but an outside entity. Worse, that because of this, that person can rule them.
The position that blindly following Sylvanas is wrong and the Forsaken need to self-actualize is immediately removed when one of the most prominent Forsaken characters in this expansion, indeed the only prominent Forsaken Horde-side immediately abdicates the chance to take responsibility and instead looks for a different, nicer messiah figure to lead them. In fact, it's a worse case than with Sylvanas because Sylvanas actually did do things for them and formed the state and she had to work and pander to receive their support, as well as in the new canon, suppress their individuality. Calia is actively sought out by the Forsaken to worship because they don't know what to do without a figure like her even though she's done absolutely fuck all. That's pathetic. It makes Sylvanas, the antagonist, right, in her reading of them.
