In Crucible that is...
Not sure why everybody is concerned over pvp balance because Xur sold RD. Its definately overrated. I think people overlook RDs piss poor RoF, and solely focus on the high impact.
Just go buy a Coiled Hiss PR from the vanguard lady. You won't regret it. The high RoF and supreme stability move than compensate for the impact. Seriously, it freakin ownz hard.

COILED HISS PRO TIP: TL-DR: Do not use perfect balance! This beast is the fastest shooting gun per damage that is a primary legendary. It kills faster than the auto rifles ever did, and kills faster than any other pulse rifle class besides red death. If you use HIGH CALIBER ROUNDS you can completely exploit the high ROF flinch this gun afflicts enemies with. In fact, it is so effective on this gun because you already have counterbalance. Try it. You will consider it not just good but competitive with the last word and thorn and snipers all in one 30 round killing machine. Source: I play a lot of PVP
