So as the title states, realmlist is set to .ru not .com. Client has been downloaded from the download section on the warmane website, and I'm not alone with this realmlist oddity. Asked my guildmates to check theirs and they reported the same.

Odd thing, I swear it was .com when I downloaded it initially when the client was just released. Then the magnet link changed to a different one.
