Not really, if you read my comment you’d know that killing Sylvanas and getting their lands back + their people out of the msw would already be enough, but as things stand, none of these 3 things could come true.
If justice was to achieve on the Horde alone, they’d have to completely dismantle it and make them unable to ever hurt any innocents again with the intention to make them suffer in the maw (really blizz?)
Isn’t there something datamined where Nathanos gets sent to the maw to meet with Sylvanas?
