Just want to start with saying that this is not a troll post! Even though some stuff is pretty "meme-y"
Anyways!
From what i have seen happening in Legion with her i've just become totally speechless, she's more or less like Yrel now. With the sudden Warchief stuff to the stuff with the lantern AND her not accepting death as she's supposed to!
Now let me be clear with that last statement, everyone knows that the forsaken will die out without something that can keep them afoot, like the val'kyr. Sylvanas has been saying this alot since cataclysm and says she's fighting for the forsaken, but now it seems like she's just fighting for herself. The "forsaken" as i see it from her viewpoint is just Sylvanas Windrunner, the Banshee Queen! And her loyal subjects..... To me it seems blizzard has dun goof'd with how her storyline has become, from being ressurected by Arthas after getting killed by him, to wanting revenge, to having nothing to do and lastly taking the val'kyr from the scourge to herself for creating new forsaken. I remember playing WC3 and really hating Arthas and being compassionate for Sylvanas due to what happened, but right now i'm utterly disgusted. Is she being written to become a Villan alá Lich Queen? Will she get a cheesy redemption story *cough* illidan and Xe'ra fanfic *cough* feat. Fuccboi Nathanos? And also i want to bring up Genn, that poor wolf. He lost his son due to Sylvanas wanting to forcefully take Gilneas (I know that it would be a strategic point of defense for the horde and Garrosh etc). And the way the Stormheim scenario played out i hope she realizes what she is doing. She deserved to have her hopes and dreams crushed for all the stuff she has done.
Now one thing is pretty damn retarded about the forsaken and sylvanas story. If she is removed, what happens then? Who will represent the forsaken that can be on par with Sylvanas? So many questions, but i'd like to discuss it with you guys. Input is a good way to create theories!
