To be fair, Anduin has chance for some awesome story telling. As we know Blizzard, they will probably botch it in the end, but hope it wont be the case. I am horde player but I actually like that Anduin is this little guy, who will tremble in moment, when he see something bigger and stronger than puppy, that's why he need his doggie daddy, but I have feeling, daddy will die soon and Anduin will be for a first time tested, if he is true leader or just another whiny Alliance character. I hope for the former. It could actually shape Anduin into really interesting character in the lore.
Sylvanas is badass as always, but there is not much what they can do with her, until situation will change in some big way. So for now, I am really looking forward what they can do with Anduin.
