It's such a weird situation since you do not allocate hits unless you precision shot, you merely allocate wounds. Which makes the whole, "Look out sir!" thing kind of... pointless since the psyker is the one hit although a wound goes elsewhere?
I dunno I just want whatever the judge says. I'm not overly worried about the whole screamerstar or that one jackwagon in a space marine unit. I'm just happy with the ability to screw over tyranids even MORE than I did before. Oh and LoC's.
