Why did DICE get rid of the laser painter on the scout helicopters on battlefield 3

In the update they had to get rid of some stuff because of trolls and noobs. Like the USAS automatic shotgun, they had explosive rounds for it, but nobody could stand a chance against it so they got rid of it. The Laser Painter probably got removed because it was to easy to kill. They did this to improve the game especially for new players who don't know what they are doing.
