Originally posted by Lord LucienNo fighting requires pure physical energy with force aid. We see Palpatine instantly killing a jedi, taking Leia out, and mortally wounding Brand, with lightning, while he was dying. Palpatine even hints to Leia that he does not have to be physically capable to defeat them with lightning. Although the dark side was too strong with Palpatine, and was taking a toll on his clone. But that is not the case with Marek.
Since was simply "extending your arms" the prime instigator of Force Lightning? You do remember that when someone is physically drained, that emitting tens--hundreds of thousands of volts electricity through your body at the behest of your mental willpower isn't exactly a walk in the park. It's not like turning on a light bulb. By that rationale I could say that "since when does physical exhaustion affect the way a Jedi fights? It's just the Force after all."
Granted, Marek wasn't exhausted, but dueling Darth Vader promises to be a taxing enterprise. He's not gonna spend his energy reserves in a distraction move. And Lightning would be a good distracting move. It's fast... not crippling no, but Vader would still block or dodge it.Are you telling me Marek was not trying to kill Vader; that he was only trying to distract him?
Dorian, Galen wasn't a maximum potential. He had barely begun to tap the immense power he wielded. When Galen struck Vader with FL think of it as a one-two punch. Galen unleashes FL and Vader is forced to block and then he has to defend himself against powerful lightsaber attacks. That is very very difficult. If Vader hadn't blocked the TK, then there is the possibilty that Vader's life support armor would suffer severe damage. Galen was more than a match for Vader.
Sidious 66, Galen had the chance to kill Vader, but the Emp offered him to take Vader job. Instead, Galen made the choice to sacrifice himself to begin the Rebellion.
