I agree with Commodore, the pro pipes do require a lot of skill, but most people just launch the grenades randomly. I liked in BO how you couldn't fire any launchers for the first 10 seconds. The pro pipes need good aim because of the trajectory and the super low damage (in MW3 at least) and you only get two grenades.
