So I just maxed out OM and had about 60-70 Motes and decided to waste them all buying Exotic Engrams so that I could get some Exotic Shards. As I went to our favorite blue man and guess what I get? A higher Base Strength and Intellect OM. I won't lie. I bought my old OM from Xür last time he sold it...(last week?) and this time it was from an engram...but with higher stats. Wtf?
