Hey, Nobbel! If Sylvanas becomes a problem in a later expansion, what do you think she'll do and how do you think we'll have to deal with it? I really hope she doesn't die because she's my favourite character. Also, do you think Alleria will return just in time to help deal with her sister?
Check out the end of my sylvanas video, speculate about your question :) http://youtu.be/9z-Et1N8bv4
