Agility Loop

So today I decided that I wanted to try and relive ten years ago when Starcraft was released and bought Starcraft II. Go ahead Jiloty...if you read this feel free to say NERDS! Anyhow, when creating a Battle.net account, I was a bit nonplussed when only certain special characters were allowed for the password for my account.  Huh?  I realize this is probably a limitation of some legacy code or software riding on Battle.net, but this seems like something that should be a thing of the past.  I have run into this on other sites as well, some of which are fairly high end enterprise sites (although Battle.net at this point is pretty damn high end).  By limiting the special characters that can be used for passwords, Blizzard is limiting password strength artificially.  Granted, password strength is a bit overrated when users are probably using pet names or school mascots as passwords...
