Thats system as long gone dead after ARR. Sure there was sparkle of sch dps but rest was pretty much tanks on tank stance moving boss,whm was the main healer and etc back on coil. But current meta is Damage. All the job are dps,green dps, blue dps. Right now green dps sucks in terms of gameplay, Blue dps as gone too much change to be boring and dps are starting to get same treatment going the easy route.
