You're talking to probably the only person in the game with the skill level to use it competently in Crucible. I've been bothering Bungie for nearly a year to make 4th Horseman the standard for shotguns, not Matador.
Not really my problem. I'm getting better with the shotgun, and if I can manage a mastery of the quote 'worst shotgun in the game' just imagine how quickly they would nerf shotguns if I started getting 40+ kill games with anything that can compete with a fusion rifle for range. I'm practicing for the same goal with Dreg's Promise as well.
It's a fun weapon, so I can play their game and enjoy it too.
