Any gun that has been buffed (I mean really buffed, not nerfed and then tweaked to make it a little better such as with the Vex) keep it as is. Any weapon that has been nerfed in any form or fashion...simply un-nerf it for PvE. No need for Bungie to say it's impossible because the shotgun buff proved that they can tweak weapon stats without them affecting PvP. Let the players love their weapons in PvE again. Un-nerf all weapons and weapon types for PvE that have been nerfed in any form or fashion due to PvP complaints or the popularity of a weapon or type of weapon.
