Models in a unit cannot be allocated wounds if they are out of range from the firing weapon
That one's going to cause a lot of arguments, mark my words.
You ain't kidding, i can hear it now.
Big units with multiple types of guns with multiple ranges are going to be a nightmare to figure out and will just slow down gameplay.
Actually I don't think it's as confusing as you are fearing... here's the actual quote:
Q: When making a Shooting attack against a unit, can Wounds
from the Wound Pool be allocated to models that were not within
range any of the shooting models when To Hit rolls were made (i.e.
half the targeted model are in the shooting models’ range, and half
are not)? (p15)
A: No.
The key phrase is "any of the shooting models". You only check whether a given targe model is within range of ANY firing model. If it is, then it can have wounds allocated to it. No need to track WHICH wounds came from WHICH firing model.
I agree with that interpretation, but again, just because it seems clear you doesn't mean it won't cause a lot of arguments.
Adding to the problem is that it is proposed as the counter to a negative. (there's probably a specific linguistic term for that) If wounds can't be applied to a model that was out of range of ANY of the firing unit's (not models's really, why are they making this harder than it has to be?) weapons, does that mean that wounds can be applied to a model if SOME of the weapons could reach that model, even beyond the number of wounds inflicted by that particular weapon.
It doesn't, really. That's probably what they meant (maybe), but it's not what they wrote.
And it's worth noting this is actually in contradiction to what is written in the BRB (which has you only check range to initially fire, not wound, but has you check LOS for both), meaning it really should be an errata, not a FAQ.
