Makes me wonder if what Garrosh saw during SoO was what Sylvanas will actually make happen. I'm talking about the phase when we fight him in Stormwind.
Anyone who thinks there need to be more scenarios, raids and quests in order to show how evil Sylvanas is must've missed a lot of context to a lot of the ingame content. Her character's done a lot more than most villains in WoW ever hoped to. At this point it's just a matter of how bad the wrapping paper type of lore surrounding her survival is. A character having a huge fanbase has a limit when it comes to the fanbase being a justification for keeping said character around.
