Melee and Physical Ranged classes do this already, where whenever you use a weaponskill on an enemy, the game automatically turns on auto-attacks too, so why not for casters/healers? Obviously auto-make up a much smaller portion of our damage, but it's still completely free damage that can add up to a gcd or two over the course of the fight depending on the class, especially since recent raid design has been to have full or near-full uptime for all eight party members. I've never understood, going all the way back to ARR, why casters and healers have to manually turn on auto-attacks when other jobs don't.
