Sometimes when I do the Taken variant of the Pyramidion strike, about a third of the way through I STILL get dialogue from Ikora talking about Eris, and how "maybe I'll meet her someday". I DID -blam!-ing meet her! She sent me on a quest to kill Crota! I'm sorry, but when you strip away 3 years of items and leave me with only a few lines of dialogue, you could at least make it so that the dialogue actually -blam!-ing works!!!
Are you getting the veterans dialogue for the other missions/instances?
