I'll start by saying this: I love this mod. It threw me out of my usual factorio loop, while not being complicated for the sake of being complicated(i'm looking at you bob).
The only problem i had with it, was ore enrichment.
It is just not worth the extra effort (and ups hit) to do it.
If it brought back the 1-1 ore/plate ratio, it would be ok, but the way it works, you might as well slap a few more smelters.
