I was v disappointed with how the sleeper simulant quest was ultimately handled... At one point there was real intrigue on the forums everybody engaged in a search for clues! But in reality all that actually happened was someone flicked a switch at bungie and low & behold the great sleeper simulant quest was at an end. As a year one player I also cant keep shaking that constant feeling that all the grind will be made irrelevant again upon the next change of course in destinys future - if they truly have a 10 year plan for this game I really don't see how that is achievable without a more drastic update (adding a new race / more unique destinations - snowy Enceladus?) that doesn't just reskin/recycle old content.
