It was because of what Sylvanas was doing to Derek. Trying to twist his mind and turn him into her puppet. Which makes her no better than the Lich King.
The Horde are not the Scourge. It’s free will or nothing.
Sylvanas was always about free will for the undead though, now she’s starting to force undead to do her will. She’s becoming a lot more evil which is plainly obvious and the ‘betrayal’ by Baine isn’t surprising.
I’d argue torching thousands of innocents is much worse than enslaving one guy and Baine decided to sit there and do nothing when she did that. It makes no sense for him to suddenly rebel because of Jaina’s family issues when Sylvanas probably did something even worse that same afternoon.
Stop twisting my words to make it seem like I am defending Jaina. I am defending Baine. Who you claimed acted completely different under Garrosh- when he didn’t.
None of this should be “new”, to a long time Horde player. It amazes me that you seem to not know his character at all.
Show me where I ever said he acted completely different with Garrosh? And idc if you’re defending Baine or Jaina. They’re both best friends that don’t have the Horde in their best interests.
