I don't want randomized legendaries, I want uniques.
Ever since Fallout 4, Bethesda has been doing legendaries as randomly rolled gear from legendary enemies and end-of-dungeon crates. Ever since Fallout 76, they've been doing them with multiple effects, with Starfield doing them as common (1 effect), rare (2 effects), and legendary (3 effects), and now Exotic with Starfield's latest update (4 effects, the forth must be crafted yourself from a limited list of options).
I hate this system. On its own it's not the worst idea in the world, but it has gutted the idea of unique weapons, and most legendary effects simply suck. What's "legendary" about 15% less melee damage in a game where melee enemies are rare? What's "legendary" about a little bit more carry weight capacity? Uniques are few and far between now, and most of the time the only thing "unique" about them is their name, which you can change on any weapon. Their appearance and effects are almost always identical to non-unique versions, which is just boring and disappointing. I'm not expecting an entirely unique model, but at least do something different with the texture. Starfield's "Ember" pistol is a good example, making a skin that makes it stand out from standard Solstice pistols, even if its legendary effects are not unique.
I want legendaries/uniques to feel like they do in Diablo: Truly unique-looking weapons and armor with unique effects. They should be rare or only given out by specific quests. They should be build-defining. They should always be exciting to obtain. But most of all, they should be UNIQUE. Unique models and/or textures. Unique effects you can't get anywhere else.
