In the most recent 10.2 build, the amount of Crests needed to create an Enchanted Crest has been increased!
Edit: It seems that Aspect Crafted gear was increased in item level though.
On the Patch 10.2 PTR, the amount of Crests needed to create an Enchanted Aspect’s Dreaming Crest has been increased to 60 Aspect’s Dreaming Crest from 45. The price of crafted gear has gotten even more pricy, especially when players will only be able to get 90 of each Crest a week (down from 150).
