Removing Year 1 exotics is a poor choice from a purely gameplay perspective and removes variety from the game. Unlike legendary items which can be replaced with a new version with bigger numbers and similar perks with little to no changes in gameplay, exotics carry with them unique perks which can functionally change playstyle and add variety to the way we play the game. So unlike replacing a +10 sword with a +20 sword in an MMO expansion, obsoleting Year 1 exotics is more like taking away skills and replacing them with different ones. Everyone would obviously be upset if the Gunslinger, Defender, and Voidwalker subclasses were removed after announcing the three new subclasses; it would take away major gameplay options from the player. Removing Year 1 exotics works in the exact same way on a smaller scale. Items like Pocket Infinity, Patience & Time, MIDA, or Saint-14 are irreplaceable in terms of function, and removing them removes available choices from the player. This isn't just about Gjallahorn being used as a crutch (after all, it can and will be nerfed), but rather about taking away content. An expansion should expand upon the gameplay options we have now so we can have an even wider arsenal of weapons and playstyles to choose from. We shouldn't be paying $40 to have content removed from our game.
