Remember Bungie, the goal is to balance the game. Not make things unusable. A 15% nerf is probably fair and I suspect they’ll still be good DPS choices, albeit not the clear “must use” choice. With that being said, if they’re still somewhat popular, resist the urge to nerf them into the realm of uselessness. Their balance comes from the need to land precision hits so this should make them balanced AND still usable.
