Correct me if I'm wrong, but I have like a 1/100,000 chance to find a legendary/exotic engram. Once I find the engram, and decrypt it, then I have to go through another RNG process, so another 1/100,000 chance of it actually being the blue/exotic item. The odds seem pretty shitty since I have to grind to get the engram and then once I have it, I could still be -blam!-ed over for a green through another RNG process? seems broken.
