Just about every single gun and armor piece from Forsaken is now worthless
The Dreaming City & Tangled Shore may as well not exist
Everything relating to the Forges was completely removed, and I highly doubt that they'll ever bring back Ada
Everything relating to Opulence was completely removed, and if the leviathan ever returns you can 100% bet the Menagerie wont come back
Gambit has been changed so many times it's hardly the gamemode it was when it first came out, and 99% of all of it's weapons have been sunset, making it practically worthless to play
So far the ONLY thing remaining from Forsaken that hasn't been eviscerated by Luke's grand vision has been Last Wish, and even then I doubt it will stay that way for long, it's foul how they're essentially charging 40 dollars for a raid and some exotics, since nothing else in the expansion is usable in the slightest

Of course, he hates it, it was the best expansion in this entire game and he had nothing to do with it so he can't take any credit for it. Luke's work is the base game and CoO that almost lost the entire player base when the game released.
