What's wrong with Sylvanas?

First I need to start by telling you guys that I rolled my first toon in wow, not because I was all into the faction war, or the fact that I fancied the lore behind a particular race. Nope, not the case. I wasn't a horde fanboy neither. I rolled my undead priest because I loved Sylvanas with all my heart. During Vanilla, TBC and partially Wotlk I loved every bit of lore behind this character. The pain, the rougery, the vengeance. Then I started liking forsaken as a faction, and tolerating the entire horde in general. But I can't, I just freaking can't stand to what Blizz done to this character in Cata and MoP.
To those who are not familiar with the lore:
The Wrathgate happened because Sylvanas trusted a Dreadlord. That's right, she trusted a demon, and let him oversee the research on the new plague. What could go wrong, right?
Shortly after Lich Kings death Sylvanas goes all crazy and decides to commit a suicide and jumps off of the Icecrown Citadel. The Val'kyrs save her life though and offer her a pact. Well, she's pretty much like a cat nowadays, 9 lives and emotionally unstable.
Then she begins raising her own army of mindless servants. Not caring at all that she's becoming the new Lech King v.2.0. After all she's been through, she decides to make others suffer equally. I mean, teh fcuk?
In "War Crimes" she's plotting together with Vereesa in order to poison Garrosh. The family reunion makes Sylvanas very happy and she has those "feelings" again, the ones she couldn't have during her undeath life. She offers Vereesa a place in Undercity and Vereesa accepts the invitation. Yet Vereesa changes her mind shortly after and Sylvanas is again all bitter and crazy.
We all know that Sylvanas is a bit mad, but Blizz wants to make her look utterly retarded. She's like a woman during her menopause. I kinda think they're planning to make her a raid boos in the near future. What do you guys think? Does her character development even make sense? Do you like her "vanilla" personality more than her modern attitude?
