The Uther conversation points to Sylvanas not being FORGIVEN, because it shows that it was still Sylvanas the whole time instead of some Bad Half.
She’ll do something good at the end of course, but she definitely won’t be forgiven for all the bad she did and her successors in Calia and Voss point to her being gone for good from Azeroth. Not to mention no lore reason Horde would ever accept her again.
It’s like Turalyon on the throne: Blizzard didn’t set this up just to have Turalyon give the throne back when Anduin comes home. They set up plot threads and follow through with them most of the time. Vol’jin Warchief is a notable example of this NOT happening but considering how many players are fatigued by Sylvanas and Anduin I’m pretty sure they will not be in the next expansion/both will be dead or incapacitated. Maybe Anduin in a coma?
Edit: Though I do have to wonder... the soul gem is kind of pointless, because Sylvanas realized the Jailer fucked her over BEFORE the gem came out. So I guess the reveal was mostly to show the Jailer had corrupted her since she was killed.
Also surprised nobody has mentioned that the Uther ghost in Vanilla/ Wrath is now called into question. Now that we know it wasn’t his good half, was it actually real?
