Yeah THIS specific quest wasn't available without the switch being flipped.. but other stuff has been, or at least partially accessible, with clues right under our noses. I didn't mean the end rewards are available right now.
Wasted time? Half the fun of figuring this shit out is.. figuring this shit out. I understand you want everything laid out right in front of you with clear steps on how to get to each reward, but I just disagree with that approach. Strongly. Every game does that and Destiny already has plenty of it.
Personal preference, I much prefer this mysterious approach. Every little thing you come across in daily missions could be a clue for something else down the line and it has spawned tons of treasure hunter type groups dedicated to combing over this stuff every day. Go in there and tell them they are "wasting their time" doing what they do. I bet they'll disagree too.
Where I do agree with you is questlines that just say "ok now wait til Wednesday to progress any further." That kind of stuff sucks but isn't what I'm talking about here. I don't want the game telling me on day 1, "Hey if you do this daily mission on October 3rd, and instead of finishing the mission normal, you go this way and do this thing, you'll get this reward." Way more fun (for me) doing it this way.
I'm not sure if you misunderstood my post but I'm totally for the mysteries. I even said I'd rather this be a set of complicated riddles that were in the game from the start instead of a switch flip. I do think the people looking for this gun beforehand were wasting there time but it's no fault of their own and that's really crappy. I just don't like that it was forced to happen on this day and then we are made to wait. Not to mention the Warsats involved.
