This seems odd, to me. I accept, and will play how the FAQ says to play it, but I think that it should be the actual target only. Why should another model take the critical, when the weapon hit dead-on to the target model. Does this mean that a structure (like a building, bridge, tree, etc.) takes a critical hit, even though the weapon was aimed elswhere?
I could see the target taking the critical, but any other affected model or terrain should just take a normal hit. Further, this compounds my other question regarding Direct Placed Templates and how there is, currently, NO chance to fumble with these weapons, nor score a critical hit.
