After reading the New Jedi Order series, I think the writers decided to give Luke Skywalker better fighting lightsaber skills which are similar to the prequels than in Episodes 4 to 6. Well, after reading and imagining how the writers describe them fighting.
I also got a better understanding of how a Jedi feels and fights with the Force. They fight with lightsabers witht he Force. All a long, I thought they fought just like that. It was after reading the New Jedi Order then I realised that the Jedi use the Force to guide their movements to block incoming slashes and jabs and also to somusault into the air and roll here and there.
In the New Jedi Order book, Traitor, Jacen uses Force Lightning to hurt Vergere but it causes his hand to hurt. Apparently, the lightning burnt his hand. Why did that happen to him when others before him like Jaina, the Emperor and even Count Dooku never suffered this?
By the way, the "spider thing" that attacked Obi-Wan Kenobi in the arena is called an
acklay .
