This setup is actually designed around working with a Razer Orbweaver and two thumb buttons on my mouse (Logitech G502) that get remapped to Shift (left grid) and Ctrl (right grid) for modifiers. I've designed this to work more extensively with my warrior since that's the only thing I've primarily had time to play, but when I have played alts, this UI configuration comes everywhere with me so that I can play with my orbweaver as it's basically ruined me from playing WoW with a normal keyboard. >.<

If you have questions or want to watch it in action, I stream Tuesday through Thursday on Twitch, Facebook, YouTube and Mixer.
