You are on console I suppose? From what I know the higher you have and can handdle the better it is. Use the highest you can at the moment and add 5 to it, play with it until you are comfortable with it then raise it again by 5, repeat until you reach 100 or close so you don't feel a difference when using a saber.
Also I don't know if you have aim assist or whatever it is named turned on or if it works independently but there's a feature that make your crosshair lock on on someone even if you are off when you aim down sight with your gun. Abuse it, if they are close aim down sight for a fraction of a second and then go back to normal view and aim with your movement then instead of your right stick, you should keep your mobility doing so. If they are far away hold it or hold it until you are fully scopped and then let go, then do it again and repeat this pattern to still aim and have as much movement speed as you can get.
