As far as I'm aware, Tyrande basically just wants to throw soldiers at the Horde for...no specified reason in the wilds. But Varian comes along and explains it's likely to be a trap blah blah.
Now loads of people, NElf fans especially, are annoyed because they think it was done to make Varian look better. (Even though he's still like a human/wolf god...-thing-)
I reckon, now hear me out, there was a mix-up in the script. -Varian- was supposed to be the hothead in this scene, being the anti-Horde he is. And Tyrande, being a several thousand year old being and a priest, was meant to be the reasonable one. Simple really, someone in the editing of the VA script must have gotten the names in the wrong places and presto, muddled up scene. They probably didn't go back and change it either due to time constraints, or the scene was already animated and implemented and released before it could be fixed. Changing it now way post-release would look...awkward, right?
This theory makes the most sense to me anyway, thoughts?
