There are many changes coming to Destiny 2 with The Witch Queen expansion, and while some may seem more substantial than others, such as the Void 3.0 update, even smaller ones can have a huge impact on how the game is played. An example is the Gambit rework detailed in the last TWAB, which is something Bungie has been very secretive about for a while before revealing all the details at once. There are no massive changes to Gambit with The Witch Queen, but those that are being made are aimed at solving a few issues with the game mode to make it more enjoyable after years of leaving it on the back-burner.
