If a character has a high DEX (say 80) they should get a bonus die at point blank range, in this case 16 feet.
The rules say that long or cumbersome weapons (shotguns, rifles etc) don't gain the bonus as they are "less easily brought to bear on a moving target at close range".
At a very close distance ie. standing next to someone I would agree to this but with the DEX example above would that really still be an issue.
Never having handled a shotgun or long firearm I'm no expert, but I would have thought that a target at 16 feet away wouldn't be too hard to keep a track of with a long weapon.
Any advise?
