The point is all 5 people do every "role" in all fights, and is not "well I am going tank spec, you go heal spec", every person is doing all 3 roles to prevent focus fire upon 1 person, to keep everyone up, and to revive those who get killed and may not have something they can kill within the down state time and to mitigate as much damage as they can between dodging and casting medium CD mitigation spells.
