Why wouldn't you want to see the PP effects in the drone camera view when the pilot that is using the camera is shot?
From my point of view it is best if effects to the pilot also show up if he is currently controlling a drone.

I even have a lot of vanilla LG shells missing to land on target even if I use the artillery computer.
So I needed to resort to a scripted solution (based on ACE laser designation) for LG shells to work.
