Personally, rumble is a completely useless feature for me. Even with an actual timed rumble to something going on, it never helped me get into anything. I usually turned it off if it was an option. The only reason I liked rumble, was because it made the controller heavier. I feel the PS3 controllers are too light.
Only time can save the world now.
