Dashing nerfs your combo damage potential.
Scaling in fighting games now is insane. Most of the time, the scaling comes down to how easy it was to get the opponent in that scenario. if the option you chose made it easier, the damage gets scaled more, and the opposite is true for more difficult options. Dashing makes getting to your opponent easier, so doing this will inevitably nerf combo damage. Doesn't mean don't do it. Just be mindful.
