How to unlink a WoW account from Bnet Account?

i have a wow account i havn't used in months and want to sell it...

But my SC2 account is on the bnet account and woW is aswell how do i unlink it or link it to another account?

 

I don't believe you can.

 

you can transfer your wow stuff to a new bnet account aslong as the new bnet account has the same name

 

It's not possible to "unlink" it.

 

once an account is linked to a battle net account, you cannot transfer it off of it. you can change the email of the account, the address, etc. only things you cannot do is change name and un-merge accounts
