So maybe I'm missing a key point here, but if you have to unlock the exotic in your collections to focus decode it, which would allow you to claim it with legendary shards, why would you waste two exotic engrams and an ascendant shard on focused decoding exactly? Cause I don't see the point. I could see it if it would allow me to narrow down what I am claiming to be in the pool of the item I want, or allowing me to get the exact exotic I want, but if I can't do either of those and can only either go RNG or claim from a pool of items when I have that entire pool, why would I not just RNG?
