Every now and again my double bladed lightsaber bugs out and it appears to only have one blade activated. It looks AWESOME: http://i216.photobucket.com/albums/c...7-25-57-95.jpg
Even back in KOTOR I used to wish that the various lightsaber forms had animation differences as well as stat differences. I would love to see this in SWTOR.
I wouldn't want this high on the list of priorities for game updates, but one day it would be awesome to see the offensive saber forms using both blades, and the defensive form switching to a single blade.
