First of all, there is a slight problem with the targeting system: There IS no targeting system.

You target what you happen to be looking at, so when there are multiple objects in front of you, like, say, all the time, you'd better accept the fact that no matter how dead-on you are, you'll still wind up targeting an innocent droid that happens to roll by like a special needs child on a wagon at the wrong moment. The good news, though, is that you can still use it to brick a Stormtrooper's face.
