I read Myrron's Guide to Blacksmithing last week, and he detailed how if you Extract an item that you previously made, you get far fewer Inspiration points than if you Extract the same item that was made by somebody else.
I assumed he had to have encountered a bug. There was no way this was working as intended.
Sadly, he was correct. When I created a Level 4 Dagger and Extracted it, I got 27 Inspiration. When I asked a buddy to make me one and I Extracted it, I got 204. That's almost a 10x difference.
Generally, I think ESO's crafting model is very good. This, however, is TERRIBLE. Even if you convinced me that for some forced-cooperation reason that this was a good idea (good luck), the fact that the difference is almost 10 times more points is just way too much to justify.
