See man. Everything we do in missions from the Dark Below had none of this.
I still felt like it was "go here and kill stuff".
Despite that there is grimoire to read, it often seems that you have to sort of piece it together and really, this should be in the game.
It seems much more interesting reading this now but if this was all included in the missions, that would have been a story.
But no.
And the way destiny is,
Will it ever be like this?
