I said that one side has to be the aggressor, and thus in the wrong in the modern view of war. In the War of Thorns, Blizzard has embraced this. The Horde is unequivocally the aggressor. Sylvannas is driven by the old vision of war as a strategic tool.
I think this is the only correct way to do faction warfare, but there are a number of Horde players who are deeply unhappy over this turn of events. Especially the Horde druids who don't want to attack Malfurion. (I, on the other hand, am looking forward to dispatching him.)
The other part is that the Horde players have their fingerprints all over this conflict. Unlike Theramore, their characters are involved from the very beginning. (And there isn't even a Kitten of the Horde to motivate them.) Blizzard finally put the major event into the game, rather than having it in a book.
I quite applaud Blizzard for taking these decisions. If you're going to do faction warfare, commit 100%.
The questline is quite good as well. It's about 45 min to 1 hour or so. Given that there's another questline on the Alliance side, I think that's a solid amount of content for a pre-expansion event.
There are also several World Quests in Darkshore after the quest finishes. Apparently Darkshore is hilarious if you have War Mode enabled, with lots of PvP going on. I haven't tried that yet, though.
I'm looking forward to seeing the resolution of the War of Thorns. I hope Blizzard sticks to their guns. Even up to having the player being the one who burns the World Tree. That would set the forums aflame.
