I had the same happen to me when I moved countries, but I kind of understand it too as there is a whole industry of stealing and selling WoW accounts for a lot of money.
So I steal your password and account, sell it off (who buys stolen accounts? What do I know): Why would you need to change the account country?
I literally just wanted to change the account country to .. give Blizzard money. Anyone with access to one of my (now) two Battle.Net accounts can play my games and use anything in-game. What is this address verification actually protecting?
Yeah but once you're verified you're not asked again - if anything, stealing an ID verified game account only makes them worth more, because they can't be generated using bots anymore.
