You don't seem to understand why the lack of ramifications is jarring.
I don't know if it should be a raid, scenario or dungeon or even simply a questline or event that happens during the SoO but something has to happen to Sylvanas and her Val'kyr that puts her in her place by Alliance hands.
Her current storyline is getting out of control in the way that she has so far gone out of her way to provoke the Alliance and even the Argents and yet nothing has come of it, and now she's continuing to do the same shit during a time when there is meant to be a tenuous alliance between the Horde and Alliance to bring down Garrosh. Her voice lines indicate her Val'kyr have gotten more powerful.
It is jarring to have somebody pull of so much shit as Sylvanas as of late and just have the Alliance forget what's happened. As it stand the Forsaken story appears to be in it's own snug little bubble where they can do what the hell they want and nothing will be done or said about.
As it stand her doing the same crap and getting away with it is just bad story telling. I'm really hoping the rest of the voice files and raid content prove otherwise or else for Alliance fans the SoO will instead be a table flip moment and not a fist pumping moment for the Alliance.
