For pve there shouldn't be anything other than buffs and exotic reworks. If there's some game breaking bug or exploit then, yes, fix it but otherwise don't nerf. For pvp I think bungie really should up the damage for all primary weapons to make them a little more forgiving and more capable to handle special weapons rather than nerfing special weapons. The reason why special weapons are so heavily used right now is because they're so easy to use. Nearly all primary weapons require the player to be a top marksman to get the optimal ttk for that weapon while specials are simply just point and shoot. Buffing primary damage would help to give players a sporting chance against the apes, voopers, and snipers. Just my two cents about it.
