Not so long ago, you had Ada's weapon mods in game for one week. Players got to use those mods for maybe 3 days after the pre-requisite challenges were completed. Of course, hardly anyone bothered. Now, you've put weapon mods behind legendary weapon orders with a drop-rate that makes end-game exotics look common! I've done over 50 weapon orders and I have 2 mods. TWO! I just don't understand why you build something and then make it next to impossible to get. It makes no sense. UPDATE: doing orders alone won't cut it. You need to do fireteam based activities to get gains on the legendary bar (below the list of orders). I can also confirm, doing higher tier difficulty encounters does not appear to add more gains to the bar than Quick Play Vanguard Ops. BOTTOM LINE: getting the armor mods is a grind AND subject to the mercy of RNG gods. New low Bungie.
