I haven't seen any input from Bungie on this. If they ARE intended to be single-use now than: 1) that should have been made clear in the changeover to armour 2.0 and 2) why weren't our armour 1.0 versions brought up to 2.0 versions? do they seriously expect us to farm for new ones after they just made the old ones useless?? and since I deleted all my old ones after they claimed to have 'fixed' the new ones in some patch notes. simply adding an exchange will not be enough, I won't be happy unless they are changed to the way EVERY OTHER ARMOUR 2.0 mod works. I'm really getting so sick of all the inefficiencies and oddities in this game because of Bungie making stupid choices.
