It would be nice if we could use case sensitive passwords and even better alt+753 type of things (alt+753 = ± ). I dunno about the alt thing would it mess up but atleast casesensitive. I watched some year old password hack test on IT magazine and their systems couldn't hack password that looked like "Itw4sTyp3dLiketh¶s" because of cases and the mark.

Also dont ever use same email you are actually using specially with things like msn. hotmail etc accounts are under constant hack snipes.

Not really sure it would help much, given how many people fall for phishing scams and wind up with keyloggers on their systems. Just spend a day in the Customer Service Forum (I think it's called In-game support for EU) and see what I mean. All the clever passwords in the world mean nothing if you hand them over to hackers like lollies.

An expanded character set wont keep people from falling for phishing attacks and I doubt that anyone seriously tries to get passwords by brute-fore as this can easily be countered by Blizzard.

Assuming we know the password length, which we do not, and assuming every character we can use has an alternate printable character via the shift key which they don't, allowing a larger character set via caps etc would still be far less secure than adding an additional character. imagine you have a 10 character password in lower case. now make one of these characters able to be upper case (it doesn't have to be) note: extra keystroke required(shift key). the password has at most twice as many possibilities(yay?). now take an eleven character password, also requiring one extra keystroke. Assuming you have more than two keys on your keyboard, a longer password is far better and takes the same number of keystrokes. Just as easy to remember, many times more secure.

Of course, most people don't choose good passwords anyway even when educated. They're difficult to remember and take time to type. Passwords aren't really the issue though. There are far easier ways to getting access to an account (not an arbitrary account) than guessing the password. For example, if it doesn't matter which account I got, I could just email a bunch of random people asking them for their password. It clearly works.

TL;DR:
get an authenticator. Update your software. Don't be stupid.

Good luck with that, there's far too many different systems involved for that to work. Unless you want everybody to switch to Unicode...
