One thing you won’t have access to – if you are reading this pre-Witch Queen release – is the various season passes. If you want a one-stop-shop to own everything prior to Witch Queen, this is your best bet. You’ll also have access to a new subclass in Beyond Light as well as various Exotic quests that will net you Exotic weapons.
You won’t be locked out of older activities like raids or dungeons from previous expansions and you’ll have access to the Shadowkeep and Beyond Light campaigns. This will get you most of the content in the game (with one exception). This is a sole purchase that comes with the Forsaken Pack, Shadowkeep, and Beyond Light.
In January 2021, the company quietly released the Destiny 2: Legacy Collection. Bungie has actually made this relatively easy recently.
