Bring back Commendations and use them to reforge guns. Here's how it would work. You level up Vanguard/Crucible Get a commendation Go to gunsmith Select gun you want rerolled Once you use commendation its gone You get 3 RNG rerolls to choose from If you like one of the rolls you select it If you don't like any of the rolls cancel out If you think traditional commendations are too much too often then make it so you only get a commendation from levelling up the gunsmith only. A simple compromise to allow some reforge but not enough to break the game.
