Who are you to say how they ought to do [i]anything[/i]? They never showed No Time to Explain, then a month or two later there was suddenly a new quest marker for people allowing them to get it. They never showed any exotic class items either. They can reveal or not reveal whatever the flying fvck they want, when they want. If you're not open to the possibility that they simply didn't mention them on purpose, then you're just being negative and close-minded.
