It's been a while since I read them, but no I didn't get that impression. I read the first few Mistborn books a couple years ago and had some of the same issues as you. Some people really enjoy how every little detail of how the magic works is explained in different ways more than once. And in that way Licanius is Sanderson-lite I guess. It's not overexplained at all. And not everything is explained in detail because the focus is on other aspects of the story and characters.

Personally, I prefer books that go even further away from the hard magic. Like Earthsea and Lord of the Rings. But Licanius is a good middle ground that I still enjoyed. Same for Name of the Wind and The Fifth Season, both of those have a detailed magic system that is understandable, but the pages of the book don't revolve around it.
