No defense against it, once ur painted in the area.. you're basically toast... nerf it or remove it.

As far as I can tell it does only two things, it increases the damage of the missile and it allows launchers to work against targets they wouldn't otherwise work against. Ground based launchers can attack air targets and vice versa. It doesn't fundamentally change the way you deal with incoming missiles. It's still a matter of using your flares and retreating before they can lock-on again.
The red laser coming from the laser designator is quite observable, so you may choose to look around and see where you're being painted from. You can then see whether you're able to engage the target.
