I have a US WoW account I just checked thank god not hacked as of yet ...well may be I spoke too soon now. Anyway I checked about buying Mists alone digitally but it will not allow me too. I can either buy Cata alone or buy Cata and Mists together for like 28% off. What if I am not interested to level beyong Warth for now ,so I cannot buy from the site I guess. This is a real bummer cos I'm not sure how far I will play and do not wish to purchase Cata...any suggestions ?
