I can't believe EA is denying any hacking into their database. Myself and tons of people I know playing GW2 have been hacked. I have never been hacked in my decade+ of online gaming. I'm very careful about my accounts, using complicated, different passwords for everything, I even have multiple e-mail addresses.
Sure it sucks I lost my stuff, but it surely is not at my fault. They changed my password, which requires the CD key for goodness sakes. o_o
