It's mediocre for the rest of Destiny, but for sisters and oryx, it's pretty fricken good. It's not a need have though, I doubt Bungie would put themselves in another Gjallahorn corner. 2 of us in our raid group have jade rabbit and thousand yards with triple tap and spray and play. One of us has black spindle and the others have 310 piercers. Never had a problem with the raid.
