False, the Vindicaar was never property of the Lightforged. It was Velen's and the Draenei, whom were already part of the Alliance.
Captured and rescued by heroes, almost killed by Saurfang just chucking an axe at him. Wouldn't call that overpowered.
I mean, it's really clear who started this faction war lol. The Alliance killed miners to get their hands on Azerite under the order of Shaw. There were no hostilities and no weapons until SI:7 started killing miners. There was literally the entire other side of Silithus that they could have gotten Azerite samples from, instead they decided to kill miners for samples.
We're talking about who started THIS war. There was peace, there was unity, until Genn put into Anduins head that Sylvanas is the reason Varian is dead. There were skirmishes, but now we're talking about a war.
It's mentioned twice in the whole book, once in the prologue and once in an early chapter. She talks about how later in the book it would be great to have peace, Anduin caused this whole mess, by bringing Calia to the meeting.
This is completely irreverent. Blizzards intent has nothing to do with how the lore is. The lore shows, as I've stated several times, that Shaw started this war by killing innocent miners. Being a member of an opposing faction doesn't make you evil or instantly mean that if you see them you gut them. Sylvanas was willing to give the Alliance once more chance after they fucked her over after she broke free from the Lich King and Anduin blew it. She had the chance to kill him right there and the Alliance would have been splintered for just enough time for her to get to Stormwind and ransack the city and raise a new Undead faction, but she didn't kill him or any other member of the Alliance, she only killed Calia...hmm I wonder why.
