On September 18, Iron Banner returned to Destiny 2 for the first time since the launch of the Forsaken expansion. Since Iron Banner's release, Bungie has been monitoring the mode, and the developer isn't completely content with what its seen.

In a blog post, senior designer Jeremiah Pieschl wrote, "One of the goals we have for Iron Banner is that it's an opportunity for lower-Power players to catch up or reengage in their pursuit of Power. Based on [player] feedback and our analytics, we're not meeting that goal." In response, Bungie is rolling out two changes in Iron Banner, which the company hopes will level the playing field between high-Power and low-Power players.
