I would personally prefer the Photon Dash to initiate similarly to how games like NieR Automata initiates sprinting. You have a very similar layout (a dodge button that initiates sprinting) but the distinction is that in NieR Automata you immediately sprint if the game detects a movement input as you are dodging. This means that if you are only intending to dodge, you don't need to move but you aren't animation locked in this so if you do end up sprinting and moving around it helps you get around the area.
In New Genesis, however, you are animation-locked in the dodge and must hold the dodge button for what is nearly the entire duration in order to start the Photon Dash. If you compare this with the Step-Jump mechanic from the original Phantasy Star Online 2, it is noticeable how much slower your dodges are as a result. I would love to cancel our dodges once more with jumping or even the Photon Dash for more nimble mobility as the movement is relatively clunky if you aren't counting frames and pacing yourself to match. It does not help me that by playing classes like the Hero, Phantom, Etoile, and Luster that you had significantly more control than what New Genesis currently grants.
