So many people complaining about Sylvanas taking out Teldrassil when honestly reading that explanation it makes perfect sense. Teldrassil is like a gigantic Alliance fortress right off the coast of Kalimdor that could be used to conduct attacks on the Horde with ease. They even have a little strip of land in the form of Darkshore where they can land their fleets. She sees that the world is about to gain a new, super powerful resource that could be used to make powerful weapons and so she decides that it's better to act now than later when war has broken loose again and Alliance has fortified Teldrassil further.Teldrassil is in a very similar situation as Cuba was in during the missile crisis if you think about it and if nukes hadn't been a ticket to annihilating mankind, that situation could have very likely devolved into a full scale war in the real world as well. Hell even with the threat of MAD it was really close so attacking Teldrassil and taking it out as a preemptive defensive move makes all sorts of sense and doesn't imho make the Horde evil by any stretch.
