More so when the game first released or new DLC had dropped, but the excitement to see what new exotics Xur was gonna bring was a fun addition to the game. You Tubers were making videos so you could locate him, and Guardians were saving currency to scoop up a new exotic they hadn't gotten yet. Fun times! Miss those days. Fridays seem dull without this in Destiny. Hope Xur is used more in 2020!
A few have said this in comments below, but Xur still serves this function for new players of Destiny 2.
Each week, do you not feel excitement for the Exotic Engram that has the potential to grant armor at high stat rolls?
