Artificer skull is nearly useless in power supply interruption missions

I just noticed that the servo skull barely attacks anything that's farther than arms' reach in these dark missions.
The damn thing is so near sighted that tagging targets far(ther) away does nothing.
It only start to fire when they are roughly entering your illuminated area.

This combined with the issues with smokes and psyker domes makes some serious shortcomings for the little buddy.
