Step 5: Dont bitch and whine about it in the forums
After VOG and Crota they gave up on the idea of some raid weapons being awesome compared to non raid weapons and overcompensated a bit by making all KF weapons bad compared to non raid versions of the same archetype. But you know that before you even start the raid, so just dismantle your loot and move on.
that's why I love the gun. it is nerf proof
