Use the following strategy to get rid of the TIE Fighters when trying to pull the Star Destroyer out of the sky. The rocket engines are the preferred way of dealing with the TIEs by gripping them and throwing them at the fighters. However, a better way is to stand behind one of the pillars on either side of the platform (the left side recommended). Wait until the fighters fly by, heading off the screen, then do a double jump. Then, Force Lightning when they fly by. From there it is a matter of timing to know when to jump. This is a lot easier and does not reduce your health bar as much.
