Make every legendary and exotic weapon have an "Adept" version that can be unlocked by accruing points for that weapon by doing multiple number of things 1) use the gun in any combat situation to get a small amount of progress 2) dismantle a duplicate of that gun to get decent amount of progress 3) turn in gunsmith materials to get a small amount of progress You could make a collection book that organises all the legendary and exotic guns in the game, so you can track your progress for each one. Almost like a stamp collection book. Casuals will passively get points for their most used guns just by doing their weekly stuff. Hardcore players will have a new goal to work towards by trying to get multiple adept guns. What does "Adept" actually do, though? Something similar to how you did flawless version of Trials guns. It simply adds the prefix to the gun and adds something cosmetic to it. Since we have shaders already, it would need to be something different. Additional doodads on the gun? A subtle light glow (to fight the "Darkness"). This would create a little something for players to work towards.
