For games with controllers (ps4, xbox) for fighter games was it intended to use the d-pad to move and do combos or the joystick?

I have been told to ask my question on this site instead. Recently I have many people telling me for Mortal Kombat that I should always use the d-pad to move, while I have always been using the joystick.

(for own curiosity) Was the original intention to use the d-pad, and do most people use it as well?
