There is no such thing as Grand Ruler cuz Ruler was not part of the original 7 classes. But you know Nasu, he can change things whenever he wants. Heroic Servants fit many classes, if he were to be a Grand, he would be a different class.

Also, as far as I know, though many may qualify to be Grand, there has only ever been 7 Heroic Sprits who were Grand Servants cuz the Grands were summoned only once, by Alaya as Counter Guardians in response to a singular event. The Servant system as we know it is an imitation of a Grand Servants.
