I found the 8.1 cinematic actually really cool …
And I’m not sure about that free maw ticket. If that would have been the plan for him, he would have just accopanied Sylvanas.
He was meant to be there for other reasons and since Tyrande should have been abducted aswell, she was not meant to send him there.
I think it is another one of the many spits in Sylvanas soup. Like Stormheim for example.
