Actually, now that I think on it, have we ever actually seen that lightsaber blades slide along one another? Unless it's in Rebels or either of the Clone Wars shows, I don't think it has ever established that lightsaber blades will slide along one another and be a threat to the hands. So why do you need a crossguard then when the blades aren't going to slide off and lop your fingers off.
And yeah, I really am not so much feeling the Lucas on this one. And this is still JJ Abrams we're talking about. I mean the guy clearly demonstrated with Into Darkness that he has no idea what to do with the Star Trek franchise, are we expecting him to suddenly pull out a good vision for Star Wars?
Oh well. I'm sure I can watch it and complain some more on the Internet how I'm the only one who understands what the balance of the Force actually should be and none of you people have read enough about Taoism to understand how the space-Taoism is supposed to work.
