One thing for GNB I wouldn't mind changing is consolidating Jugular Rip, Abdomen Tear, and Eye Gouge into one button, so when you fire off your rotation with Continuation you hit "1, 2, 1, 2, 1, 2" instead of "1, 2, 3, 2, 4, 2". That would help cut down on bloat and free up some space for new abilities.
