Exotics are not mean to be used in raids, thats why there are raid weapons. Of course there are exceptions to this. Hunger is a strong second best to ghorn And blackhammer is almost better than an icebreaker is some sense, mostly because it is a legendary so you can still equip your ghorn and white nail kills it if you have a steady hand. I would very rarely use an exotic primary for a raid. (Of course a red death or suros for hard crota,or multi tool for the abyss) I dont even like a vex for vault. Fatebringer/revenge/corrective measure all day for that raid. Just my opinion. Exotics are all for show. They look special, they sound special, and they are special. But they are more common, and all identical. Find yourself some good legendaries and youll be much happier.
