Yeah, I suggested something like this. Holy shameless crosspost batman!
"Shotgun. If you pass a +1 accuracy roll, damage dropoff is reduced by 80%. This only applies to enemies that are on your green aiming line.
Combat Shotgun. If you pass a +3 accuracy roll, damage dropoff is nulled. This only applies to enemies that are on your green aiming line.
Double Shotgun. If you pass a -2 accuracy roll, damage dropoff is halved. This only applies to enemies that are on your green aiming line.
This makes shotguns a good alternative to the chaingun (Which they are, even at medium range in DooM 2), but keeps their AoE damage as low as it is right now.
However, this also makes Eagle Eye a staple trait for every single weapon (bar BFG), so I'd suggest removing it and making accuracy rise by 0.5 on levelup instead."
This upgrade should be applied to a 6d3 shotgun, of course. I'm fine with this or 8d3 shotguns.
