My Issue with this is, we have people getting paid lots of money to develop these games, that are captains of industry, - yet you would have thought that a silly idea such as mine would have come up a long time ago. Maybe it did, and maybe it was frowned upon, who knows. the Initial changes i Would have made to further the usage of said Enhancement Cores would be to basically build your own Exotic - Similar to what you have with armor / Weapons. You get an Exotic - Intrinsic Perk (X Y Z - Unique Valuable Trait Etc - with Curated perks (NOT RANDOM ROLLS) You can then decide - Do I want MOB / RES / REC Rolled on it (Using said Enhancement Core) (exotics can get an extra +1 per Stat Max) so lets say you have Peacekeepers with Perk Tree 1 (Traction + Submachine Gun Dexterity) & Perk Tree 2 (Submachine Gun Scavenger + Special Ammo Finder/Primary Ammo Finder) Mob +2 Res +1 Rec +0 You can use E.C to Essentially add 2 extra Stat Boosts to your Exotic = Mob +3 Res +2 Rec +0, doing this will unlock the ability to masterwork your Exotic Armor. Masterworking Exotic Armor will work different to masterworking normal armor. you choose a path to masterwork (Mob / Res / Rec). Once you have chosen said stat to masterwork, you then have to get X amount of Kills with the weapon Perks Pertaining to that Tree (1 Tree SMG Kills, 2nd tree Primary Ammo kills / SMG Kills or Special ammo Kills, or something of that sort. Once you have completed said Kills with Whichever weapon is featured in your exotic armors tree - you can now Masterwork your exotic Armor. Once an Armor piece is Masterworked - you can opt to have all perks in a tree be Enhanced using Enhancement cores.
