So true, exotics are one of slots, so Xur is there to offer us more choices. We all found some exotic pieces throughout the game, so we all have enough to play the game. He's there to complete the collections. I dont care if he sells something I already have, soon enough he'll have something I need that will offer varied builds for my caracters. I dont understand why everyone complains, either it's because he sells bad stuff or good stuff, there's always some crybabies trashing the forums.
