I don't know, but pointing an arrow and threatening one of the Horde racial leaders is a pretty big deal for me. For such an insult Baine should torn her to shreds, like he almost did in Warcrimes.As for other leaders. I don't get it. Everyone, with an exception of Gallywix and that irrelevant Draenor Lady, agreed that she crossed a line. For what they are waiting? They are waiting for the Alliance to clear their mess? They are waiting so she can send more of their people to death? And the last thing, why they are scared of her? Horde leaders acting like afraid children. This is bull&*!@.
Why do people keep saying she burned the tree because she lost her temper. She clearly explains she burned the tree because Malfurion's survival would have been seen as a blessing from Elune and stirred hope and courage in the nelfs. The plan was to sow despair and hold the city and prisoners ransom to prevent the fall of the Undercity and Silvermoon City. They could no longer count on that and she had to choose between another war that ends in a temporary stalemate before the next (which is what she was working to prevent since Greymane's actions showed plainly the Alliance leaders wouldn't stay true to any Alliance pact since they were free to defy Andy with no repercussions) or to show the Horde was no longer playing that game in hopes the Alliance would crack under the pressure and seek to defend their own kingdoms. She could then offer peace treaties from the leaders who would honor them individually till there wasn't enough Alliance left to worry about a united front when one leader lashed out because of their own hatred of a horde race.Both sides do keep copying the other's mistakes though, the alliance went in to capture the empire with no option to turn back if it went south and cemented the Horde and Zandalari bond the same way the horde initiated what was supposed to be a short war with no exit plan if they failed.This is also probably why she is taking Baine prisoner, to show that unlike the human king you can't defy her and stand with her. This war was started because Anduin is not the high king his father was and has shown he can't hold his faction leader's in line.
can I maybe make a suggestion to whoever runs your youtube. Putting "Baine and Sylvanas 8.1.5 Horde War Campaign Cutscene" contains no spoilers. however your youtube has the spoiler basically in the title. for someone who actively tries to avoid spoilers, I saw the title of the video and it was immediately spoiled.
