... I think this is a trick for blizzard to earn shit lots of money and ensure that people buy their new xpac.
Just think about it. They release a preorder to the game + that you get a free 90 on any server you want, then this bug happens. What does this lead to? That people buy the xpac and creates a character on Darksorrow -> more money and a bigger player base in the future for them.
What are your thoughts?
