So it seems like firing into melee only gives you a -4 modifier to your attack roll in PF1, which is too permissive. AD&D 2E had rules for hitting your friends by accident, if I remember correctly, so this will be the first rule we'll graft in. Maybe for this weekend if I have time to look it up, otherwise maybe someone else can look it up and help us integrate it.
I want there to be a serious penalty for a bunch of archers hanging back and taking potshots at the melee.
