I'm still leveling up my first jeweler, so naturally I'm wondering which items to break down at which levels he reaches. There are posts and articles discussing this, such as
http://www.sunshine-daydream.us/ESO/jewelry.html, but they all have two surprising aspects. First, it seems that the IP given varies only a little by the color of the item. More important, it seems like intricate pieces will ALWAYS "give" vastly more IP than actually you can get under the max-decon-IP-at-that-level cap.
Are both of these points accurate? If not, what am I missing?
