While we're told some zones will remain relatively unscathed, almost every zone will be touched in some way, whether it be simple storyline changes or more massive shakeups from rivers of lava or shrunken coastlines or war, or even more greenery thanks to shifting water sources.
So here's my simple question: Will you miss it? Will you be nostalgic for a desolate Desolace or the massive Barrens? Will you mourn for fallen Astranaar and Auberdine? I'm sure some things will be missed more than others, but then again, change can be good. Being able to move on to new challenges and new excitements has me pretty psyched all told. But then again, what if they get rid of Lakeshire Bridge? I have been waiting a long time to see that done. When the Cataclysm comes, what will you miss? What will you be glad to be rid of?
