Crimsonyoshi, you are not alone… I have been having the exact same issues as you described. I also contacted tech for GW2 and they told me the same thing- windows 8 not supported yet. I have also checked drivers, reinstalled, and used diff keyboard and mouse and cant find anything that will help. GW2 worked just fine on my old set up, just upgraded to ASUS Sabertooth 990FX R2.0 motherboard with an 8 core AMD 4.0GHz processor (was full upgrade, so I didn’t expect a downgrade in performance), and went from 32bit windows xp home to 64bit windows 8. My husband just installed windows 8 pro and did the same motherboard/processor upgrade and is experiencing the same issues. Hope you find a fix… we will definitely keep looking- I know if I find anything I will post!
