I wasn't really thinking about getting the same thing. In my moment of impulse and hapiness I only prepared myself for getting the wrong class item. It made the insult sting just a hair more as I instantly facepalmed myself. I got the helmet first thinking it's a guaranteed exotic item for my class. I then figured "why not?" with an engram gamble and a shot a second exotic item. It figures the RNG gods would mock me by giving me the same item I had just scored directly from Xur.
