I also would appriciate a Linux client for GW2.
I am tired of Windowswith all its flaws and bounderies and seeing where Microsoft goes with Windows 8 really scares me as Desktop user.
The only reason i still got a Windows system running is Gaming.
But with Steam coming for Linux activly pushed by Valve, ActivitionBlizzard porting to Linux finally i see light at the end of the tunnel !
Without a doubt Linux + openGL is capable of doing all the fancy gaming stuff Windows + DirectX can, it simply needs more Support by big studios just like ArenaNet.
You already developed a MacOS client. Bringing GW2 to Linux is only a little step further. Stick to Ubuntu just like Valve, force more Standards and soon we might have a platform for the future of PC gaming.
