I'm trying to understand the logic with the rest of the Horde's leaders here, even Lor'themar doesn't like her that much, you'd think after Garrosh is gone they'd give the Alliance the all-clear to steamroll her given the Forsaken haven't ever really been on board with the whole shamanistic vibe the majority of the Horde had.
Heck, the whole reason the tauren talked everyone else into letting them in was to cure them... and that's NEVER been brought up since.
I mean I get it she's 'hot' (Despite being dead, gross) she's an elf, she's got mind control, she's really central to their culture, and there's no viable replacement*, but it seems weird to ignore that she's killed a lot of people and done a lot of immoral things that have never been addressed by anyone outside of... Drek'thar.
EDIT: a clarifier, when I say Sylvanas has mind control, I'm not saying she mind controlled people using the Val'kyr or does so to the Forsaken, Im saying it's an ability she had in WC3 that attracted a lot of people to her, and her banshees have the possession ability, which adds up to a thematic that can draw people to a character that otherwise doesn't make sense.
*(No, not Koltira, he's LITERALLY done nothing but fail. Ever. He lost to Thassarian, got executed, raised, lost to the Scarlets, had to be rescued by the player, couldn't power his own runeblade, and would've lost at Andorhal AGAIN if Sylvanas hadn't brought the Val'kyr in to bail him out, heck he didn't even want to join the Horde, he basically did so because Thassarian told him to in the DK manga. He doesn't even warm up to the player like Nathanos did, he's nothing but insulting and I hope he's dead >:| )
Also Edit:
1. The Forsaken never got 'Forsaken" by anybody, Garithos got killed before he had a chance to backstab or attack them, and the Forsaken joined the Horde before we got to see them interact with the rest of the Alliance.
2. The fosaken attacks on the alliance are largely unprovoked, there's no evidence ingame that ambermill, hillsbrad, or any of those places were going to attack the Forsaken, and if the forsaken are largely concerned with being left alone and fighting the scourge... what do they need the rest of the continent for then? Moreover why fight for it instead of being diplomatic? We've NEVER seen a forsaken npc ingame discriminated against by an Alliance NPC purely on the basis of undeath. Ever.
