My main beef with RealID is that you have to add a player's Battle.net email account to friend them.

This means they know half of of what a person needs to know to hack your WoW account.

I know, I know. Only give it to real friends. That's not the point. The point is, there have been Blizz reps all over the official forums telling folks to make a special email address only for Battle.net, and to never give that email out to anyone (since, after all, it's half of what a person needs to access your account, authenticator notwithstanding).

Now we have to give this out to people if we want to make use of this new feature? Let me make it clear that, as an altoholic who is deeply rooted on her home server and has ten characters on it, I was very excited about being able to communicate with my friends from any server I choose. Even if I only use this with RL friends, which I would, it just seems like too great of a security risk.

Plus the lack of being able to use a pseudonym bothers me. Even on Facebook I don't use my real last name. *shrug*
