Ever since the shift to the seasonal model, Bungie has been making constant improvements to Destiny 2 as well as the way seasonal content and story bits are delivered. This led to Year 4 in Destiny 2 being one of the best in its history, and it bodes very well for the release of The Witch Queen expansion in February, and the launch of Season 16 too. However, the seasonal model has changed a bit since its introduction with Season 8, and the main differences reside in what players get from the Season Passes.
