[Double-bladed lightsaber why must we use this?]

Is there a significant lore reason that shadow's have to use a double bladed lightsaber? I realize that it's a manner of distinguishing the class but I don't understand why they couldn't provide me the option of using a single lightsaber (the quintessential Jedi weapon of choice) and still use my class abilities. Was this perhaps an animation issue?

 

no its not an animation issue. Jedi shadows are specialized assassins who use double bladed light sabers to slay their foes. If you prefer 1 handers go sage.
