You can't even bloody compare the two. Whole Vanessa story is locked to one area and then a Rogue Class Hall bit. You want to get the full Sylvanas story? Then yeah, you have to go further than bloody WoW, because she was not even introduced in WoW to begin with (durr).
What you get ingame is enough to connect all the dots, but if you want more - you need to leave WoW safe space. That's how it works with big characters, just the same like with Lich King, Illidan or just about every bloody big character we have in WoW, apart from true WoW babies like Anduin.
