The Masterworks weapon system was one of the most significant gameplay additions to Destiny 2 since its release, as it essentially functions as an entirely new weapon tier. But, as it is a brand-new mechanic, there are some issues that need to be worked out. Recently, Bungie revealed what sort of changes are in store for Masterworks.

In a forum post, Bungie stated that it has listened to feedback from the player community regarding the system, and it has formulated a list of tweaks to address concerns. Most notably, Bungie plans on improving the consistency and frequency of Masterworks drops.
