Shotguns seem to be the only good guns in crucible. I mean I don't think it's fair how powerful they are so I've tried not using them but if you wanna win it's like you have to use them. I see Bungie nerffing them in the next update thou. I have no idea how that's gonna change the game play. On thing I wanna say is that I don't like that you have to get through someone's shield ( the white line part ) before you can actually do enough damage to kill them.
