The perk was a gigantic factor. Removing it will make high impact low rate of fire shotguns actually realistic , in game speaking. You should not be able to zoom in and suddenly have all your shotgun pellets focus fire in a tight grouping. It doesn't make sense. Now a high impact low rate of fire shotgun won't be useless , not by a long shot , but it will require more skill and getting up closer so more risk. More impact should equal more risk.
