It's funny, but Blizzard's been playing this game for years with their two-factor auth, particularly the part where people's accounts without two-factor would get compromised and the thief would then turn on the two-factor auth, thus making it that much more difficult to recover the account. Blizzard's been doing this for longer than Google has, maybe Google could learn something.
