Its a mix of nostalgia and destiny 1 actually being good. I personally believe if you compare destiny 2 to destiny 1 destiny 2 is as good as right before the taken king launched. forsaken fixed soooo many issues so much that I was very surprised when I joined back. annual pass isn't made for fixing things just adding new content, this next fall expansion most likely rise of iron size will most likely bring destiny 2 to where it was after the april update. But this is my opinion its gonna take time for destiny 2 to get better but one its at the end of its life cycle I think it will be a bit better than destiny 1.
so at the cost of however much by way of dlc maybe Destiny 2 will be a "bit" better than Destiny 1.
That sums up everything that is wrong with Bungie. The Division 2 has launched, building on where the first game left off which is as a sequel should be. No waiting a year and 3 dlc for the game to be where it should have started from.
