Most of our acocunts can't register is because our age was not set in our battlenet account. If you try to change your country of your account to Singapore it will still say you're not eligible. When i emailed customer support it was because my age was not set as when we all merged our accounts back int he day there was no option for age at that time. Customer service then ask me to email them a soft copy of my passport and they subsequent changed my age (have to be done throught his way or phone call)./ After this i am now eligble. The only thing is customer service emailed me and mention that changing account country just to be eligble is wrong and if they find out they will disqualify you.

So for those who want to risk it you can try it this way. I'm not very sure i want to take the risk.
