i remember it was possible to attack drones with fire and forget missile but now these are invisible to the tracker so you cant fire at them at all with any kind of f&f vehicle, the chance of hitting them was not very consistent but you could sometimes destroy drones which was very helpful since these things can become very problematic if they spot you specially in arcade but in recent patch this is not possible anymore, is this a bug or a just nerf? these things were already hard to fight with autocannons (unless you use HE-VT or some anti air vehicle with enough missile to spare for drones)
