1. I heard somewhere that Alliance players would have a chance to take vengeance for Southshore at some point. Is that true?

2. Does any of the Eastern Plaguelands end up de-plagued so to speak after the questlines?

3. Which old world zones have the most overall phasing?

If these questions have been answered somewhere along the line, I apologize. I have been trying to refrain from reading quest text, and watching videos of said quests. I know what happens in most zones, I'm just trying not to see it all before the release.
Thanks
