Star Wars piece i have been working on in between client jobs for the past few weeks. Tried to implement more 3d into this one to see how it would work, and i like the result so think i'll use it more!
Actually, two individual lightsabers really are more dangerous because your opponent can't use the other blade's position as a reference point to always know where it is like they can with a double-blade lightsaber.
Eh, depends if you know how to USE two individual lightsabers. It strikes me that, especially with a hilt-less weapon like a saber, you would be in great danger of slicing yourself open. Even most two-bladed fighters use a sword and a dagger, not a sword and a sword. Otherwise it's too complicated.
Mind you, I can see the case being made that someone who regularly fights with two being more dangerous than the man used to one--though that's more dependant on their respective skills, not on the amount of lightsabers they're carrying. What I mostly object to is the sort of power-up shown in the SWTOR trailers, where a Jedi/Sith who habitually uses just one, simply grabs a second and instantly becomes twice as dangerous. It makes little sense.
Just to step in here, it doesn't show too well but the sith here is blind. And has already killed 4 jedi, so 2 more really isn't much of a challenge. He is so strong with the force he doesn't need to rely on sight and knows what his opponents will do before they do. Basically the 2 jedi here are walking corpses.
You need to remember Sith/Jedi can use the Force and thus have vastly improved reflexes, among other things. I doubt there's real danger of them cutting themselves. Of course there should be some practice involved to be able to use two lightsabers effectively, but I reckon Force users may also just have an increased capability for adaptability.
