It’s completely normal for ongoing live-service games like Destiny 2 to fluctuate between highs and lows in player counts between the game’s major updates. As more and more players complete everything each past update has to offer, it’s typical for many to take a break, and then return en masse when new updates are released, with new game modes offering more loot to chase. Destiny 2 is no stranger to this pattern, experiencing a cycle of frequent highs and lows since the original Destiny was first released over a decade ago.
