Difficulty is so Meta. By which I mean, if you and your friends choose to preserve the activity difficulty by NOT doing [i]any[/i] research on how to clear the vault...it'll probably make you all throw-yer-controller mad several times before you finish it. I'm guessing that a lot of people are going to look up the inevitable raid strategy writeups put out by the people that clear it first, and then they'll bitch and moan that it was too easy, and blame Bungie-kins for not giving them more content to cheat-clear. Stay strong. No raid research. You won't be alone.
