Mate, SUROS was king before the nerf. It was the most used weapon. It was basically where Thorn is now. Be honest with yourself, it was crucible which caused the nerf. I've nothing against crucible players, I pretty much split my playtime 50/50 between PvE and PvP but pretty much every nerf has been the cause of PvP. But, they did make pulse rifles a load of fun so there's a bonus.
