lol.. the new breed of "Saber-snipers"!!!
I don't know. Yeah sure, you'll probably get loads of this to begin with, as people will be experimenting with it and stuff. And I spose it's a covering attack in a way; letting you get closer as the thing is hurtling towards your opponent. Even then it's a distraction for them, forcing them to block or something.
Of course it's dependant on mana consumption. You can't do that continually I take it? And there's a clip in one of the trailers, I forget which, where a dark jedi throws his lightsaber at Kyle, but he blocks it successfully enough.
So.. not sure. You're not going to continue throwing it when you are forced into melee by your opponent.
