For a game that has lasted as long as Destiny 2, with consistent events and updates coming to try to bring new experiences to finish, any developer is bound to run into a few design hiccups. Bungie has recently had to auto-complete a task in the latest questline for the Iron Banner event, that revolved around getting kills with a specific type of weapons.
According to the Bungie Help Twitter account, the auto-complete was done as a result of player feedback, specifically due to the way that the quest was changing player behavior during the PvP event. Surprisingly, the task is nothing new for Destiny 2, but the way that this request of players weighted the need to complete it as the second step in the "Saladin's Gauntlet" quest was causing issues for the event as a whole.
The specific step in "Saladin's Gauntlet" that has been causing issues, was the second step, which tasks players with gaining kills while using heavy weapons. This has been the part of quests before, but due to the fact that nearly every player running through Iron Banner was attempting to complete the whole questline before, camping around heavy ammo drops started getting out of control. Some players using the Sentinel subclass for Destiny 2's Titans had even reportedly been popping their Ward of Dawn bubbles on the heavy drops instead of capture points, because the resource had become so desirable.
Normally, this type of quest step in Destiny 2 wouldn't be such a hassle, except for the fact that it combines a normal task with the limited nature of the Iron Banner Event. With only a limited number of attempts over a relatively short time to grab all the heavy kills needed, players had quickly started hoarding and camping the ammo that refreshes on a two-minute loop during PvP matches. So, it's understandable that incentivizing this type of playing had been damaging to the experience of the event, which is why Bungie was quick to make the changes needed to get the game running smoothly again.
There have been Exotic quests in Destiny 2 before that have similar steps attached to them, sometimes against AI controlled enemies and other times in the Crucible. This is likely why Bungie would have thought nothing of it when implementing the same task for what had to be the hundredth time at this point. It all comes down to the specific set of circumstances that led to the negative feedback from players, which goes to show that it's really only a difference between a few variables that can drive player behavior in one way or another.
Destiny 2 is available now for PC, PS4, PS5, Stadia, Xbox One, and Xbox Series X/S.
