Triumph for the Iron Lord title is locked at 14/15 unique IB weapons with no way to get the 15th weapon to "pop" for the Triumph. From my understanding, this has been an issue for over a year with no acknowledgement from bungie regarding a fix. I'm a returning player from D1 and this really took the wind out of my sails. Not only is the "new player experience" a complete fustercluck, our time and effort aren't important. Weird strategy for a game that desperately needs to attract and retain a healthy player base.
