On range- had to think about this for a while, and in the end, going to go with this- we all know the ranges in meters of our weapons. If you think it can probably hit, you can write it into your post. Mechanically, all your weapons are still combined into the single roll, and all the damage is combined into the single value.
What determines the damage is if you are in the same or adjacent or distant zones, and a bit of random arbitrariness. Generally, you'll either be in short or medium ranges anyway. Long and extreme ranges will be more roleplaying exercises.
Resolving what we have now.
