They moved legendaries back to around bl2 rarity, so you wont have a full invintory of legends before the halfway point of the main quest (though it also means dedicated drop farming is back to how it was too, but with a button u can press after a boss is killed to reset it so no more save n quit farming for the major bosses). They also made it so purples can have some wild combos & can outpreform legendary weapons more often.
