So a friend of mine and me we're farming for some exotics (mainly the Bad Juju) when we both got an exotic leg armor engram. He had the theory that we'll get the exact same thing from the engrams and he was right. I don't think it's a coindidence since we both got the same type of engram and the same pair of boots. EDIT: Yes, i know that there are only 4 pairs of boots in the game. But as someone stated in the comments below the same happened to him but with the twighlight garrison, weird isn't it? EDIT: i am specifically addressing exotic engrams in this thread.
