You could still use their "repelling shot" attack and then immediately use that gap closer move in the video and stay in melee range so you can immediately go back to spells/melee attacks.

Except by the looks of it RDM is being specifically designed with the intention that you have to use melee attacks to achieve maximum damage and not using those melee attacks would be akin to a SMN not using their DoT's or a BLM not casting fire spells.

Edit: That could be entertaining to see (and not in a good way), Red Mages that refuse to use sword attacks because "mage."
