Destiny should implement tower weather and NPC decorations for specific holidays, or even seasons. A large majority of MMO's such as WoW or Guild Wars change their "tower" based on the specific holiday. It would have been amazing to see snow at the tower, and perhaps a large beautiful fire right in the middle of the walkway to the stairs. And for Halloween, perhaps make the tower completely dark with only candlelight at each vendor station and the screams and howling of tormented souls on the wind. Food for thought :)
