Weve seen community discussion around XP gain in Destiny. After reviewing our data, we agree that the system is not performing the way wed like it to. Today, wed like to describe whats going on under the hood, and talk about what you can expect going forward when it comes to earning XP in Destiny 2.
Currently, XP will scale up when playing longer or fixed duration activities like Crucible competitive multiplayer matches and the Leviathan Raid, and XP will scale down when playing activities that can be quickly, repeatedly chained, like grinding Public Events. We are not happy with the results, and weve heard the same from the community.
Effective immediately, we are deactivating this system.
