Returning to the game: Looking for help with a Darth Vader/Sith inspired build

Hello everyone, I am returning to the game after some time away. I decided to play on Core difficulty and I want to create a build inspired by Darth Vade/Sith Juggernaut. I am planning to pick the Kinect Knight class and follow the path until I get the Plasma Sword. I would really like to hear your advice on whether this is a good idea or if it is too unviable for Core difficulty.
