Guess who burned down Teldrassil. It wasn't Alliance nor Jaina. Nope. The Real Villain who burned down Teldrassil was Sylvanas all long. Yup after all these crazy theories of who burned it down. It was the Banshee Queen herself.
This isn't much of a surprise since Horde has already started the war of Mass Slaughtering Innocents of Night Elves across Kalimdor and invading their homeland by destroying it. So yea Horde is a evil faction. Sorry to those of the horde players who didn't really see the truth of the faction. As long there's a Warchief doing evil crimes of killing innocents, destroying lands, and wiping out all life on Azeroth. The Horde will never be a honorable faction.
Yup Sylvanas is Lich Queen 2.0
