I guess what I'm confused about with rapid fire and scatter shot is you make one "hit roll" and multiple "wound rolls".
Does that one hit roll count and one hit, thus the wounds are processed in a batch?
or
Does that one hit then fork into multiple hits with each wound roll process sequentially?
I.e. does the number of hit dice you roll dictate the number of "batches" you roll for wounding?
Using your example with the 2 pistol shots, would it be:
scenario 1:
- pistol 1 hits and rolls a 2 on the rapid fire dice, getting 2 wound rolls applying the results in parallel.
- pistol 2 hits and rolls a 1 on the rapid fire dice, getting 1 wound roll after pistol 1's wound results have been applied
or
scenario 2:
- pistol 1 hits and rolls 2 on the rapid fire dice, it rolls wound 1 and applies the result, then rolls wound 2 and applies the result.
- pistol 2 hits and rolls a 1 on the rapid fire dice, it rolls its wound and applies the result after pistol one has sequentially applied it's wound results.
In my mind I see the one hit roll as a volley, and that volley is processed at the same time in a batch, so I think scenario 1 makes more sense? That said my mind may be wrong

.
Although in scenario 1's case there is now a mathematically optimal order in which to resolve the hits, which feels not great. Unless you roll the hits separately too and resolve things as they come

. i.e. you don't get to choose the hit order after seeing the hit results. In that regard, maybe scenario 2 is the correct way to play, albeit slower.
