Nice, I liked the new email specially for WoW. At the moment I'm just using my 'proffessional' one, but ye, I use it for other things than WoW as well. So I think I'll make a new one for WoW.
Although the authenticator is really nice. I'd rather see it to be needed only at account management. Cause it can be quite a hassle to use it everytime you log in :/
