is it possible to change to korea server? thx for you time

no.

but i dont need a location in korea for buy a korean version ?

You can get the digital download.

I believe he is referring to the fact, that you have to provide a Korea specific ID in order to buy a Korean version. There was a guide to circumvent that on Team Liquid.

nope he doesn't.

he can go to korean bnet and download the digital from there.

then he adds the key he bought with the digital download to his account.

Game Region Warning
You should change your country to Korea, republic of and verify your Personal Residence Number to use Korean games.

Aren't the Taiwanese and Korean server merged?

Are you sure?
Did you try it firsthand (or second hand?)

My understanding is, that Korean law requires Blizzard to get someone's Korean ID (a social security number?) to allow a Korean account.

When I try to buy something on kr.battle.net, it redirects me to eu.battle.net.
When I try to create a Korean account it wants to verify my real name.

hmm

well we tried that earlier and it did work. Perhaps the new law appeared after we tried (a couple of months ago).
