I just thought of something, do you think Bolvar will "turn" evil someday, and that we need to fight him as a new Lich King? I've never been a big lore fan or anything, but I killed LK again today and it made me think of it.
For those that do not know who I'm talking about:
Bolvar was a soldier of the alliance, that went up against the Lich King, got poisened by the Forsaken and burned by Dragons breath/fire. Wich left him as a living burned man.
And when the Lich King was defeated, he got crowned as a new Lich King, as there must always be one.
So what do you think? Will we see a return of Bolvar as an evil force, making us fight the scourge yet again.
