Make personal lasers shoot artillery targets

[Luco42]

After almost dying to some biters twice I learned that Personal lasers don't target things that are being shot at by artillery. With some asking around I understand why, but I still think personal lasers specifically should keep shooting. At high Artillery range levels and especially with Quality artillery it can take a shell 20+ seconds to arrive. That is potentially 20+ seconds the lasers on you (or a spidertron) refuse to fire, putting a player (or a spidertron) at unneeded risk. I agree with not wasting ammo but since personal lasers are effectively free I say they should keep firing, trading a few potentially "missing" artillery shells for more safety.
