RDM lost some of its visual identity with the upgrade to Veraero and Verthunder III

Momentum and sense of direction were never part of the Red Mage spellcasting.

Red Magic uses one's own aether, rather than drawing on the aether of the land, like White/Black Magic. due to this (intentional) downside, Red Magic was weaker, but safer for the land, and other the centuries, as the secrets of Red Magic were discovered, methods were developed to make their spellcraft more and more efficient. Every movement of a Red Magic is a spell component, allowing them to mitigate the aether usage with more and more efficient magics.

You'll notice in the Job action trailer, the Verthunder III casting animation seems close to the Verfire animation, a more subtle gesture, but resulting in a far more impressive blast than Verthunder.

You are becoming more and more efficient with your spellcasting, and producing larger, more powerful effects. Which is the entire point of the entire Red Mage aesthetic, from their less traditional caster clothing down to the rapier they wield along with their focus.

Ver III spells are completely fine aesthetically, as they are showing your mastery of Red Magic.
