I thought since my account had nothing of real value (no heroic epics, no pvp gear, not a hell of a lot of gold) that hackers/gold farmers wouldn't even bother with me. If they're scouting a capital city and /inspect me (at the time) in quest reward blues and ah crafted purples.. and then /inspected someone in a complete ICC gear.. the account they'd want to compromise would be the one in ICC gear - even if that much research goes into who the pick to steal from.. however, after SO long of being extremely lucky that I had never been hacked amid the increase of people who had been, I ordered an authenticator anyway because one can never be too safe. In the few days it took for my authenticator to come in the mail, I got hacked. I spent a few hours just trying to get through to customer service, but I've got nothing but GOOD things to say about the guy I talked to. He answered all my questions about the restoration process, how long it'd take, how I'd get my stuff back, how my guild would get their stuff back.. how to deal with the authenticator once it came. Of course the authenticator comes with instructions. Its EASY to take it off of your account should it break - calling blizzard isn't involved.

The way I see it: 7-10 days for your account to be restored if it gets hacked, this is after however long it takes for you to get through to customer service because you DO have to talk to someone for the process to get started (at least, I'm pretty sure you do)..

OR.. use an authenticator, be in a phone app or the purchased one.. spend 5 mins or less attaching it.. and really, if you need to take it off, the same like 5 mins to remove it.

Good luck.
