It already has progressed. Nearly half (the western half) of the realms in Dwilight were wiped out. Some people moved east; a lot quit the game entirely. More than a year was given for this solution to 'work'. It has not. Players have been voicing their discontent with the mechanic; they have been silenced, and quit. Something indeed has to change; the rogue mechanics forcibly pressuring outer realms is not working.
