Force Camo is 4 secs, with a 30% speed increase. More than enough time to sneak up on a RDPS, making it invaluable to starting the fight. It's CD is relatively low, too, so it will be up pretty reliably. If they get the jump on you, hit it as well. Either it will break your snare that they put on you, or at least negate any damage and keep them from targeting you. Hit them with Pacify, which basically means they can hardly hit you for 6 seconds, and wait for them to KB you. Force leap and unload again. It's rather formulaic, and very effective. Give it a try.
