Sylvanas has been the most enigmatic character to date.
Regardless of all she did and what she didn't, she will always be a character that we have so much to talk about, because she is somewhat mysterious.
She was also not a good leader, despite a lot of people liking her character, me included. And i think she is too full of herself, she failed to see the ones that betrayed her in the past, so now she thinks she can control everything and stopped giving a thing for others, only thinking about her own self and her survival, that is truly not what a leader does, even less as a Warchief.
In a span of 8 years she was betrayed 3 times or so, she trusted Godfrey, and a Dreadlord as her closest advisor, and she got backstabbed and even Godfrey killed her, as she never thought he would and she was in shock.
She is powerful but she is for sure not omnipotent and omniscient, as everyone thinks, she doesn't see everything that is coming = that's why she got backstabbed before.
Whatever is giving her the idea that an Old God will serve Death, she can't be really sure that will happen.
I think whatever she saw on her last Death, made her want to come back and serve Death and led her to this conclusion that all life needed to be ended and feed this hungering darkness, whoever this hungering darkness is.
This hungering darkness must be really creepy because Sylvanas really hates to be the person that takes orders. She having a master is still quite confusing.
On the "Windrunner: Three sisters" comic, Alleria has voices saying she serves void's true enemy - Death. This proved to be right at 8.2.5 cinematic of the Sylvanas loyalists, where she talks about the bargain with Azshara will yet to bear fruit and that the armies of azeroth (us included) will fight her Master (N'zoth) and that he will line their streets with corpses.
Void and Death are totally opposite things, and the forsaken seems to even be immune to the curse of flesh. Which is a curse created by Yogg saron - Void.
With this being said, i think Sylvanas is too confident that she is on the top, because Void and Light need the living, so she being on the side of Death, she will win. Void (Old gods) and Light clash with each other. And she is neither.
I think she is being way too much blind to this serving Death, because all that needs the living (even an Old god) and life itself is weak and that she can manipulate anything.
At this point, i just want to see that her character will drop off this crazy idea, whatever she saw when she died the last time, made her this way. She didn't only this time died and want revenge, she now has a motive, and she is getting powerful to do what her master tells her to do.
I want to see this "Death" master of hers. Or know more about it and it's hungering darkness.
I think Sylvanas used to be a more interesting character than now. She had reasons to do what she was doing, this whole Death servings are still confusing but will still make me curious regardless. We only have a conceived ideal of what this Death is, when in truth, it's a incognito for all of us.
By now, it's 99% credible that this master of hers is the one that whispered Vol'jin. At least i believe so.
The 1% is because we can't be truly sure to be 100%. Even more on wow, we never know.
Overall, i think her character is still pretty enigmatic and that even tho she was not my warchief, as she was for some, and never will be, i will always have interest in her character development, she is also truly manipulative:
SHE WAS CAPABLE OF MAKING WHOLE HORDE BELIEVE THAT PACIFIST ANDUIN WRYNN, WOULD USE AZERITE ON THE HORDE.
The Dark Lady is probably forever one of the most favorite, well developed characters, she will always give us something to talk about.
For this reason, i don't know either if i want to see her dead. WoW needs character with charisma like her.
I love her mysterious way. I hate what she does and what she was being turned into this expansion, she is not my warchief.
But neither i want anymore warchiefs on the horde.
Don't need to agree with me, but with this whole things happening, i opened up my thoughts to you!
