Why do people still think Sylvanas story would end in a raid (killed off by tyrande) ? Didnt the devs said several times now that something like this would not happen to Sylvanas?
My prediction:
9.1 Maldraxxus Raid (kel end boss)
9.2 Sylvanas Raid where at the end (5%) comes a Cinematic Sylvnas fighting Tyrande (maybe CGI?) but before Tyrande is able to defeat Sylvanas something happens - Jailer being released etc . Similiar to Azshara and Nzoth
9.3 Sylvanas got backstabbed by Jailer as already forshadowed, at athe end of the Raid Sylvanas sacrifices herself to defeat the Jailer and dies / and is going to be imprisoned as the new Jailer
Thats the most obvious way and thats why its most likely going to happen.
