Because the game is still gonna be up for another 5 months and getting these items is just as good as getting fatebringer in y1. Think for a second. If everyone knew the dark below would raise the light and cause vault to be useless, you think people wouldve played it? Definitely. Get the gear while its still usefull. I wanna get legendary fatebringer, while its still usefull. I wanna get full raid armour for every raid, while its still usefull. Overall, just because a new game is coming out in half a year, doesnt mean the rewards from THIS game are useless. Will be, but not yet. We got 5 months.
