I love how Bungie brings back a well received idea just to turn it into crap. When Umbral Engrams first came out they were pretty amazing for being able to target your rewards and get weapons with multiple perks in the final column. It was a reasonable "grind" to get the materials and you could usually keep up with the materials needed to focus all the engrams you got once all the decoder perks were unlocked. People really liked this since it was a great farming method for god roll weapons. Every engram had a chance to be something great that you actually wanted. Fast forward to this season and the once great idea that was Umbral Engrams has been decimated into a shell of its former greatness. You simply cannot keep up with enough Hammer charges to focus the engrams. For every 1 focused at Tier 3 there there are probably 10-12 that I focus using shards. The focusing cost is so out of balance with the time it takes to get the charges its simply NOT worth it. They REALLY missed the mark on this one.
