I can tell you from experience that this will continue to be a problem with WoW no matter what you do. There have been countless others that have emailed Blizzard and petitioned them to make a native linux client, but they are scared to death that their flagship product will be hacked to bits by linux power users. Everytime you have a patch to load, you will have a hassle to deal with before you get it back running... Blizzard intends to make things difficult for linux users, it's deliberate, and your just gonna have a lot of headaches.. I recommend running it on it's native OS (windows) so that it can use DirectX like it was meant too.. it will run better, and display better graphics that way. I'm sorry for this dissapointment but it's just the truth.
