Oh I agree. Her edge of night story and the Forsaken existential crisis were good plots for her to move forward with. It’s a shame the writers decide to make a horrible mess of that. Even if they do redeem her, her progression feels really poor.
What I’m saying is, characters like Jaina and Thrall don’t really have the above left. They really need to fade into the background now. The Horde-Alliance conflict was the highlight of their narrative and that was “resolved”, and it may feel forced to keep pushing them into new stories.
Edit: another thing is character progression, which Blizzard isn’t capable of writing in a manner that feels natural, which is why they need to fade out.
