Due to the recent nerfs in the PvE area of the game very few weapons are gods for boss damage. 150rpm grenade launchers and snipers have had their damage cut by a large amount. Even though these nerds have made large boss damage harder, whisper of the worm is still decent for damage. However, whisper chews through ammo. This is why Bungie should tweet the white nail perk back to its original state so that ammo is not taken from reserves.
