Motorola Droid :: How Secure Is A Rooted Device?

I have been rooted since shortly after 2.2 dropped and it broke the SiriusXM app. I love having the ability to do so much with the phone . My question is kind of specific to an application and general to the nature of a rooted device. I have been playing World of Warcraft for 5 years now and with the always present threat of being hacked and all of my in-game items, characters and account being stolen I added the mobile authenticator app as soon as it was available for Android devices. For those who don't know what this is, it is an app which you add to your in game account and will generate a key which you put in upon login that adds an extra layer of security to your account.
