Bungie announced that the daily and weekly events in Destiny will be put on hold from September 8-September 14, 2015. This is due to the 2.0.0 update which brings in a lot of The Taken King‘s content and updates vanilla Destiny for all players, even those who don’t purchase the expansion.
All players will be able to try out The Taken King‘s crucible content with The Rift map, during this period. Afterwards it will only be available to those who have purchased The Taken King. Thankfully the experience system will remain changed for all players, eliminating the need for armor with Light ratings and instead based purely on experience earned through PvP and PvE content.
