Blizzard Korea geht das Thema als erstes an, sehr interessant.
According to today news, Blizzard Korea primarily categorizes war(PVP) servers into 4 groups:
A: alliance & horde both over-population
B: both optimal
C: horde want
D: Both want
7 servers belongs to A group, 8 to B, 11 to C, and 21 to D.

The process of character migration in WoW Korea will be going as follows.
First, 7 new severs will be created.
Second, horde players in group A can have choice of migration to one of new 7 servers.
Third, alliance players in D will automatically be migrated to one of new servers assigned by Blizzard Korea.
Last, horde players in D will automatically be migrated to one of group C servers assigned by Blizzard korea.
Then, how many really bad Alliance/Horde imabalances are hiding in category D could be inferred from above procedure.
