I was wondering about the battlenet account, so here is my current situation:
I have 1 leg. chinese id number.
I have 3 cwow accounts (one i am using, one for my wife and one for my son), so we will be playing at the same time.

my question is:
can I use just 1 id number to create 3 different battlenet accounts or do i need 3 different id numbers?

what i understood is, that you can make one battlenet account with two existing wow accounts, but then you couldnt be playing at the same time, correct me if i am wrong.
many thanks for your help

I think your idea is right.
But I dunno if you'll be able to create multiple accounts out of one ID...
