Well, I think that is the mostly likely way Blizz would tell the story, yes.
The problem with Nuance with the Scarlets now is they were definitively corrupted. You can’t really make a justification for the order itself because we know it was made a puppet of the Nathrazim.
Unfortunately, I think the nuance of the Scarlet Crusade is regulated only to the individual. The person who joined the crusade for either right or sympathetic reasons, and got manipulated and turned into a tool for the evil they sought to destroy.
I am not sure how I would tell this story, tbh. Maybe the best way would be like… So much of the Crusade has been Risen into Undeath, and the conflict is more a contention of identity rather than a physical war. There would be a clash of values between them and the old identity of Lordaeron vs the more “New Wave Forsaken” identity. The Identity of Lordaeron as a cursed Kingdom vs the Identity of the Forsaken as a people in of themselves.
And I think this can be perfectly represented by Calia and Voss.
The problem with that is, you can kind of have that without the Scarlets altogether. The Scarlets almost become redundant in that kind of story, except only to exacerbate the rivalry. The real struggle I am having is… How does this end?
Becuase I admit, I don’t really like Voss. I think she is a boring Marysue and even though I am not really a Scarlet RPer (I have 1 Scarlet I made this last year, and the RP has been primarily romantic in nature as sort of a taboo Lesbian nuns kind of dynamic LOL) I have always liked the Scarlets aesthetically, and I think their lore is very good. So any story I would tell would be bias and probably not what Forsaken fans want.
Edit: I suppose there is always the option of an undead Scarlet allied race… Like if Horde gets Alteraci humans, Scarlet Undead could be the trade off, with Calia and/or Whitemane as the Racial leaders.
Hell, Whitemane+Calia Romance, do it Blizz, you cowards.
