One thing I'm wondering about is whether in the current canon there are different "levels" of lightsaber.
That green lightsaber was cutting through those Dark Troopers as if they were soda cans. Would Ashoka's lightsabers have done the same thing?
Does this mean that the material that the Troopers were made out of is that much weaker than beskar? Or would the green lightsaber be able to stab right through beskar?
OR, was Luke using some kind of force powers to locate the exact microscopic weak points to cut them apart?
