I've been searching myself, I tried MAC Spoofing, IP is Dynamic, changing PC name, still my XUID or GUID or WETFIS wont change.
Since this client doesn't use accounts, and I can't seem to find a way to change GUID. even deleting your profile/stats doesn't affect it. I tried some old ones for other clients but they did not work.
Thanks,
