Whilst nice that it gives you what you previously didn't, i can't say that i fully understand the thought prosses of putting in armor pieces in them. Especially when you only get 2 of them. Both of mine gave me an armor piece each and from two different sets. Depending on the pieces this could be a nice thing, as they could go well for certain style, but not having the whole set is kind of annoying. Now before anyone says that this is to encourage people to spend money buying the rest of the set. I got the gauntlets of the Jade rabbit set, a set that you can no longer buy. It is also the armor set it shows you when you inspect the engram. So with only 2 engrams and a huge variety of items to get. Two different armor pieces has to be one of the most disappointing ones to get. More so since i can't even finish the set, even if i wanted to. I do like these engrams as they do guarantee an item that you didn't have and getting armor sets is cool. But with how rare they are, you much rather want something else.
