I appreciate the effort you put in here but honestly destiny is a loot based game and reforging takes away from hunting the optimal roll on gear. Now if there was a way to decipher the best way to farm a certain gun that might be something of an alternative. Another Idea is to make the perks we know now into a talent tree on our guardian so when we wield a certain type of weapon it will act as though it has the perks you leveled in your tree. This way bungie could take the middle tree perks and expand on those as what comes on a particular gun.
