Maybe this has been suggested before.
Lightsaber fighting styles. In Kotor 2 we have the saber/force forms. But THe movements are still the same as in the Pre-Empire era. The problem with that is that supposely Count Dooku's fighting style was used in ancient times, when it was common for a jedi to fight jedi. With their enemies beaten, the jedi order adapted to the times changing their saber styles to something better fit for blaster deflection, bodily amputation, etc.
